3:55 Quartz crystals are actually like tiny tuning forks. What makes them special is you can both excite them into their resonance and measure said resonance using electricity. They actually kinda look like tiny tuning forks under a microscope. Factories will use lasers to trim material off the "tynes" until the frequency is correct. 32 kHz is a common frequency because it's 2^15 cycles per second. It's easy to count the cycles with digital logic to produce an accurate clock.
To be exact, it's 32,768 Hz, which is as you said, 2^15. The frequency is so convenient for computers that they are used to count the time in every PC compatibles since the introduction of IBM PC-AT.
not every quartz resonator looks like tuning fork, only "tuning fork" type :) Most of them are quite different from that. Also, very old version of electric clock resonator was metallic tuning fork actually, but with two coils (excitation and feedback)

A decade or two ago a bunch of power customers in north-central British Columbia, Canada, complained that their clocks were very inaccurate. Lots of them were late for work.

None of the other appliances cared about the slight deviation.

Not a problem any more! In the US (and I suspect Canada and Mexico too) the frequency average is intentionally maintained so that this doesn't happen and has been that way since the 1930s or something. The variation during the day can slip a little but, but they track it and adjust it so the long term average is maintained. Wikipedia has a good article on this but basically whenever the frequency has slipped long enough for the time to be off by more than a handful of seconds, they adjust it to bring it back to where it should be. Wherever you live in the US your mains-synchronized clock will stay within 10s of the time you set it to as long as there is not a power outage.
@@alzeebum I had to create a routine in my analog clock application to keep synchronization with the computers real time clock.

I had a radio clock all the way back in the 1980s. Oh, wait. It was a clock radio. It was digital, though. It had numbers on plastic tabs that flipped when each minute changed. It went "clack!" And at the top of each hour, it went "clack-clack-clack!" It had knobs for tuning in the radio, too. Very advanced! It had a wood finish.
Sending love to you and your family. This one was amazing, i learned so much and will enjoy researching different atomic clock ideas. Your birthday story was wonderful (and relatable!). Thank you Anton.
Most of Europe gets this time radio signal from the German DFC77 radio station at 77.5 kHz. I certainly do even as I live over 1000 km from the source of the signal.
Anton, smile, say thank you, how thoughtful! And use it. Sometimes the gift means more to the giver than the recipient. From one wonderful person to another.
The superposition affected by gravity issue is very important. The proposed experiment seems doable and not particularly expensive and would put laboratory experimentation --small science--back on the map for funding. Thanks for finding it and reporting it. Unfortunately, the article is behind a pay wall for all but those with university affiliation. Please cite a free pre-print.
3:52 The frequency of the Power grid can actually slightly change by up to +/-180mHz (Microhertz) here in Europe. And yes that makes all clocks that depend on the Power grid to measure time go faster or slower...
True but those fluctuations average out - in fact the grid frequency deviations are recorded and a procedure known as TEC (Time Error Correction) is implemented which deliberately raises or lowers the frequency depending on whether the accumulated error is low or high to exactly reverse any time error. So long term it's actually a very accurate time reference
As my friends and I are nerdy and dislike these awkward gifting situations, some of us maintain a wish list of geeky goodness. It also provides fun topics of conversation.
I am celebrating because this is the first time I have more knowledge about the subject than you do, but you did very well. another good explenation, thank you!
This is exciting. Quantum Mechanics is well above my skill level, but the ability to measure time dilation at quantum level has got to move science forward. Thank you Anton.
Thinking of QFT. The particle in superposition should oscillate uniformly because each instance shares the same position in the field. What's important to their time is not their distances from earth, but how they are relative to you, the measurer. One field, one particle, one you to perceive instances in superposition sharing the same clock.
Some buildings block low frequency RF with metallic studs forming a coarse Faraday cage.. . Many power converters from lights to chargers to your neighbor's solar system can obliterate what's left.
I thought you would be talking about a discovery I read about yesterday, about an ultra-precise measurement of a transition in the hearts of thorium atoms, where they state "The discovery of a laser-controllable transition in the atomic nucleus of thorium-229 marks the dawn of the “nuclear clock.”. They use an ultraviolet laser. They realized that a clock based on thorium-229 atoms would be immune to much of the background interference that plagues the best atomic clocks since it involves energy transitions in the nucleus instead of in the electrons surrounding the nucleus. See the article in Quanta Magazine - "The First Nuclear Clock Will Test if Fundamental Constants Change". And oh, btw: You can get precise time from a GPS signal, anywhere on the planet. You don't need to depend on NIST. There must be clocks available based on this principle. Most every cell phone these days has access to precise time via the GPS signal they process, but I don't know why they don't give you the time derived from that.
Thanks for keeping me informed, Anton! As a young 20 year old I am always absolutely stunned at some of the things we're *still* finding out. Can't wait to see what's coming in the next 60-70 years
I guess I have a lot of people that believe I’m a nerd. I’ve got several atomic clocks scattered around the house that I’ve received as gifts throughout the years.
Shm... You got one of the most valuable gifts of all ~ a home with someone that loves you! So many others could only wish to be so gifted! (Pull back and take a "humane" view for a moment!)
Wow! What a time to be alive! And I'm not saying this lightly. This is a really great work. Looking forward to see the superposition of relativistic effect 😃
Beginning reminded me how much I like Stanford Research Systems (SRS) frequency standards. Their rubidium + GPS + OCXO is so good for demanding audio uses. Though the GPS part isn't really needed for audio, it's so long time window standard helper.
First off, thank you as always for a really interesting and informative vid. That being said, you're a smart guy with a lot of knowledge about a lot of stuff, and you have a channel dedicated to explaining that stuff to the multitudes of laymen out there on the internet in an easy to understand way. So yes, you very much are a nerd. Never understood why that was ever considered a bad thing, or even to this day is somewhat considered a negative label.
Cool stuff, sir. As to practical uses, there's a story about Michael Faraday (the GOAT of physics) that he was talking once with someone the government who asked him what could possibly ever be done with electric motors. Faraday told that was going to be achieved by later researchers, but that it didn't matter, because he felt certain that the government would come up witha way tax it. Wonderful work, Anton.
@@KLRJUNE Wait, don't tell me you're one of those people who look at the Pelosi's or Obama's with their net worth of many millions of dollars and think that didn't come from you. 😂😂🤣🤣 It is called laundering.
but they have the same signal in SEA, so yea, it would work in South Korea as well. the Casio Oceanus line uses the same calibrating signal, and it's built for Japan.
this is so exciting, quantum gravity has been the biggest mystery in unifying classical and quantum mechanics, being able to have concrete proof that quantum particles either do or dont experience gravity is going to be a massive step to overcoming this hurdle
@3:59. A 32.768Khz tuning fork crystal is typically made to oscillate at that frequency only at a specific temperature such as 25°C. At other temperatures, the frequency variation is typically -0.036ppm / (Tc-25)^2, Tc being the crystal temperature in Celsius. So, unless that drifting is compensated somehow, if you take your crystal watch off of your wrist, it may slow down considerably.

In the mid 70s I was a radio maintenance technician in the USAF working in the HF radio maintenance shop. To check the operation of our radios we would tune to WWV, the NIST radio station which operated on 5, 10 and 15 megahertz sending out time hacks. It would a few seconds before the top of the minute it would announce that at the tone the time would be so-and-so Coordinated Universal Time. We would set our watches by WWV and so our watches were always really close to UTC. One evening my wife and I were at a Mall when a guy asked me what time it was. Whem I told him he said, "That can't be right!" to which I replied, "It is. I set my watch by WWV this morning." He then asked what WWV was and after I told him it was the official time for the U.S. he exclaimed, "What makes that right?". I was at a loss for words. How do you explain what makes the National Institute of Standards and Technology right? How would you have answered him? Anton? Anybody? BTW I have clocks very similar to what you showed hanging in my kitchen and also in my man cave/computer room. I also have my PC set its clock with the NIST via an app. Plus I have a wrist watch made by Casio that sets itself from the NIST every 8 hours. I guess I like knowing the correct time. FYI, Anton, I think there is a version of that Casio watch that works in the Far East. It's called the "Waveceptor" and is available on Amazon. I love your videos. Keep up the great work!
In the US, AC power was made so any clock plugged into the wall would be right to within 3 seconds. Not 3 seconds / year. Just 3 seconds. Basically, the old timely plug-in-the-wall clocks were as accurate as the atomic clocks. The problem happened when clocks started using the DC ("wall wart") power supplies. *Then* they needed the radios.
Nonsense, where did you hear that baloney. An electric clock will vary 2 to 20 minutes per year and some parts of our nation have more variations than others. Texas happens to be the bests since isolated. The atomic clock that are the reference for WWV stay within 100 ns of UTC and 20 ns of the national time standard, you can't say that about the 60 Hz mains frequency even within a day.
@@RWZiggy it is possible you've used poorly made clocks. There are specifications and companies with large motors won't damage them. I've never had to re-set one of those clocks. TVs used the power grid for timing for decades.
This feels like a breakthrough waiting to happen. If the experiment can be successful in that it can measure accurately and be proven that it measured accurately, any result is a breakthrough. This is a question that even a yes or no answer would make theoretical physicists have a hayday, let alone the how of a yes or no. If they didn’t experience different time dilation, what dilation did they experience? If they did how does that work given they are the same particle? Really juicy info, makes me excited for the next few decades of theoretical physics. We had a barrier for so long where any measurement was impossible but the exponential improvement of measurement technology has provided new opportunities and will continue to provide new opportunities at a growing rate in the future. I feel like a great example of that improvement is how we got a picture of a black hole and that was a huge thing even though it was just a blur with a dark spot in the middle, and then just a few years later we have a picture of a black hole that includes the spiraling of the excretion disk.
Follow up question for Anton, or anyone smart. Scenario in vid: The Yb atom is successfully placed in a superposition, then it's grabbed by a laser tweezer, then another laser tweezer is positioned near, which then grabs the same Yb atom at another point, because it's acting like a wave, kinda. If I'm understanding correctly, when the superposition is "broken" both laser tweezers will have a Yb atom in them. The same atom, but now twice. Which is all well and good, but isn't that technically creation of matter? Or is the second atom not permanent? Or are we working with such small increments of time none of this matters cause quantum gonna quantum? I feel like I'm missing something, maybe when the superposition is broken, there is only one atom again, or something relating to the observer effect? Or at the end of the experiment there truly are two Yb atoms now and it's similar to how temporary/virtual(?) particles can borrow energy from the vacuum? The experiment itself can't be providing enough energy for creation of a Yb atom, unless it does because it's focused on such a small point, but I don't think this is the case. What gives?
Breaking the superposition just leaves you with one trapped atom. The experiment would have to be conducted with the superposition intact, carefully measuring the small differences between the two locations without actually determining the 'true' location of the atom.
Great, thanks. That makes much more sense. Side question, do you happen to know which trapped atom stays and which one disappears? After the superposition is broken. Disappears is the wrong word, but I think you follow what I mean. If we designate them as Yb1 (the initial atom) and Yb2 (the newly captured superposition "version"), when the super position is broken is Yb1 always the one that remains? Or can Yb1 "leave" and Yb2 remains captured?
I see two possibilities. First, the time dilation might cause decoherence of the superposition. The particle emits a radio wave and chooses the lower position. Given the interaction with the tweezers, I think this is more likely. The second possibility is that the superposition holds the particle in a mean time frame about midway between the two separate places. For small time shifts, this is not at all unlikely; however, I expect that larger separations will favor the first choice even more -- the difference in energy (beat frequency) will soon happen quickly enough to radiate and decohere.
I rather feel like, we might get differening wavelength/frequency within the same wave function (of the particle). So, essentially, the particle will be in superposition of two different relativistic effect as well. I think so by imagining what'll happen if a single wave of light is put in a gravity well. The wavelength will get red shifted closer to gravity, making a continous change in a single wave.
A far more interesting experiment would be about the validity of entangled particles transferring their state to the other particles instantly. If the "lower" particle is affected by time dilation more than the upper particle, that would dispell true quantum entanglement. The entangled particles would be proven to have separate inertial reference frames and therefore couldn't transmit their state instantly to the other particle.
Yes, very interesting. There could be a slight delay observed in the lower particle materializing as spin up after the higher particle has already materialized as spin down.
@chriskennedy2846 yes exactly. I'm still pondering the implications of that in regards to the properties of entanglement. It's differs substantially from experimenting with the superposition of a single particle as mentioned in the video. I will also need to spend some time thinking about that experiments implications to quantum mechanics and times effect there, as normally "time" is somewhat glossed over in quantum mechanics. Does "time" become a probability function in that experiment ??? Very interesting topic indeed !
@@John-ir2zf quantum nonlocality is a proven fact( if you rule out some interpretations) it is way faster than light at least, it should be instantaneous to make any sense.
You misunderstand entanglement. Nothing is transferred instantly. When one particle is observed, you instantly know the state of the other simply because it is always the opposite state. No data is exchanged. Nothing is changed about the unobserved particle.

Oh, wait. It was a clock radio. It was digital, though. It had numbers on plastic tabs that flipped when each minute changed. It went "clack!" And at the top of each hour, it went "clack-clack-clack!"
It had knobs for tuning in the radio, too. Very advanced!
It had a wood finish.
Well, they say it's the thought that counts 💜
I can turn off my internet for the rest of the day because I won't read a better comment.
Sending love to you and your family. This one was amazing, i learned so much and will enjoy researching different atomic clock ideas. Your birthday story was wonderful (and relatable!). Thank you Anton.
Happy belated birthday Anton. Love the channel buddy. Keep up the great content!
Most of Europe gets this time radio signal from the German DFC77 radio station at 77.5 kHz. I certainly do even as I live over 1000 km from the source of the signal.

I get it in Finland 👍
Ha! Not in The UK ... don't need any of that fancy European rubbish ..we go by the clock on the Church Tower now! :-)
The uk has used their own MSF signal from 1950.
Happy belated birthday. Appreciate your work and enjoy learning
Anton, smile, say thank you, how thoughtful! And use it. Sometimes the gift means more to the giver than the recipient. From one wonderful person to another.
The superposition affected by gravity issue is very important. The proposed experiment seems doable and not particularly expensive and would put laboratory experimentation --small science--back on the map for funding. Thanks for finding it and reporting it. Unfortunately, the article is behind a pay wall for all but those with university affiliation. Please cite a free pre-print.

3:52 The frequency of the Power grid can actually slightly change by up to +/-180mHz (Microhertz) here in Europe. And yes that makes all clocks that depend on the Power grid to measure time go faster or slower...
True but those fluctuations average out - in fact the grid frequency deviations are recorded and a procedure known as TEC (Time Error Correction) is implemented which deliberately raises or lowers the frequency depending on whether the accumulated error is low or high to exactly reverse any time error. So long term it's actually a very accurate time reference
MicroHertz, not millihertz?
A few years ago Serbia was causing the frequency to be off. Tom Scott did a video on it.
mHz is millihertz, μHz is microhertz

My wife has been “about” to buy me a bench grinder for a decade, I bought myself one 7 years ago.
😂
I'm glad you finally got your bench grinder.
Its a normal thing. Its just because you're taller than your wife. Its the same as the GPS effect
Don't tell her. Then return it and buy a bench for your grinder.
I suppose a man could live without a bench grinder, but, is that really living?
Anton, bro you got to let her give you something lol. Gift giving is as much a thing for some people to show their love as it is for you to receive it
As my friends and I are nerdy and dislike these awkward gifting situations, some of us maintain a wish list of geeky goodness. It also provides fun topics of conversation.
@@bjdefilippo447and again: it's not always about you
I am celebrating because this is the first time I have more knowledge about the subject than you do, but you did very well. another good explenation, thank you!
This is exciting. Quantum Mechanics is well above my skill level, but the ability to measure time dilation at quantum level has got to move science forward. Thank you Anton.
Amazing stuff again , bravo maestro !
I love your videos, Anton. Thanks for doing these!
Thank you, Anton. Great story and a great explanation about the clocks!
Great video, I’m excited to see some experiments coming to finally begin to probe the connections between relativity and quantum mechanics.
Thanks for sharing this, something to look forward to in the near future.
This was an especially interesting episode, Anton. I hope you update this when you're able.
Thinking of QFT. The particle in superposition should oscillate uniformly because each instance shares the same position in the field. What's important to their time is not their distances from earth, but how they are relative to you, the measurer. One field, one particle, one you to perceive instances in superposition sharing the same clock.
You are definitely a most wonderful geeky person Anton. The very best of us.😊🤓💚♾️
We will definitely need more accurate clocks when we go time travelling.
I’ve had an atomic clock for about 10 years, it sometimes get the time wrong, or takes hours to a day to pick up the signal.
Some buildings block low frequency RF with metallic studs forming a coarse Faraday cage.. . Many power converters from lights to chargers to your neighbor's solar system can obliterate what's left.
!!!!! this is the most exciting thing happening in the whole of science right now !!!!!
We've been waiting for this for nearly 100 years.
I thought you would be talking about a discovery I read about yesterday, about an ultra-precise measurement of a transition in the hearts of thorium atoms, where they state "The discovery of a laser-controllable transition in the atomic nucleus of thorium-229 marks the dawn of the “nuclear clock.”. They use an ultraviolet laser. They realized that a clock based on thorium-229 atoms would be immune to much of the background interference that plagues the best atomic clocks since it involves energy transitions in the nucleus instead of in the electrons surrounding the nucleus. See the article in Quanta Magazine - "The First Nuclear Clock Will Test if Fundamental Constants Change". And oh, btw: You can get precise time from a GPS signal, anywhere on the planet. You don't need to depend on NIST. There must be clocks available based on this principle. Most every cell phone these days has access to precise time via the GPS signal they process, but I don't know why they don't give you the time derived from that.
This is super interesting and something I've been wondering for years. I'm glad someone is finally looking at it.
Long live the Nerds Anton, I'm proud to be one too. Another really good video!
Hotel Coral Essex?
Thanks for keeping me informed, Anton! As a young 20 year old I am always absolutely stunned at some of the things we're *still* finding out. Can't wait to see what's coming in the next 60-70 years
Anton, the quantum/relativity experiment you describe sounds incredible!
I guess I have a lot of people that believe I’m a nerd. I’ve got several atomic clocks scattered around the house that I’ve received as gifts throughout the years.
have you ever compared their accuracy against each other? Kinda curious just how in sync they are
Shm... You got one of the most valuable gifts of all ~ a home with someone that loves you! So many others could only wish to be so gifted! (Pull back and take a "humane" view for a moment!)
Wow! What a time to be alive! And I'm not saying this lightly. This is a really great work. Looking forward to see the superposition of relativistic effect 😃
In Japan, the electric grid is BOTH 60 and 50 hertz, depending on where you are. 50hz near Tokyo, and 60hz here in Western Japan.
Blown away by Anton. And “Time”.
That’s amazing! I had no idea we’d come so far! So, hypothetically catching both parts of a particle / wave in a double slit experiment?
Wow great story and explanation. What amazing times we live in.
Well I've learned something interesting to know. Thanks for the video
Beginning reminded me how much I like Stanford Research Systems (SRS) frequency standards. Their rubidium + GPS + OCXO is so good for demanding audio uses. Though the GPS part isn't really needed for audio, it's so long time window standard helper.
Wow. This is 🤯. Super cool and important stuff.
I loved that intro, it was educational and endearing!
Wow. I live in Alaska. Looks like the clock wouldn't work here either! Great discovery to share -- thank you!
This would be freaking awesome! Let's do this!
Anton in S Korea you have coverage of two atomic time stations one in Japan and other in China
First off, thank you as always for a really interesting and informative vid. That being said, you're a smart guy with a lot of knowledge about a lot of stuff, and you have a channel dedicated to explaining that stuff to the multitudes of laymen out there on the internet in an easy to understand way. So yes, you very much are a nerd. Never understood why that was ever considered a bad thing, or even to this day is somewhat considered a negative label.
11:20 "maybe they actually don't care about Einsteinian principles at all." LOL Something I imagine Douglas Adams would have said :)
@Anton, you are picky with your presents! ❤ 😊
That was fascinating, Anton.
I love a good horology video. Well done, Anton!
Cool stuff, sir.
As to practical uses, there's a story about Michael Faraday (the GOAT of physics) that he was talking once with someone the government who asked him what could possibly ever be done with electric motors. Faraday told that was going to be achieved by later researchers, but that it didn't matter, because he felt certain that the government would come up witha way tax it.
Wonderful work, Anton.

@@Deletirium I think we can take that as a certainty. But this channel has a wide reach, and Faraday is not known as well as he should be.

Haha dude! I would love to jear how your frist date with your wife went!
This was your best intro ever! :-D
but they have the same signal in SEA, so yea, it would work in South Korea as well. the Casio Oceanus line uses the same calibrating signal, and it's built for Japan.
You've got attention and desire to give, Anton😊 That the best birthday present🎁
this is so exciting, quantum gravity has been the biggest mystery in unifying classical and quantum mechanics, being able to have concrete proof that quantum particles either do or dont experience gravity is going to be a massive step to overcoming this hurdle
Happy Birthday Anton 🎉🎁🎊🎈🍾
Anton has that Sheldon Cooper energy at home
Happy birthday Anton.
Thank you very much for the video.
@3:59. A 32.768Khz tuning fork crystal is typically made to oscillate at that frequency only at a specific temperature such as 25°C. At other temperatures, the frequency variation is typically -0.036ppm / (Tc-25)^2, Tc being the crystal temperature in Celsius. So, unless that drifting is compensated somehow, if you take your crystal watch off of your wrist, it may slow down considerably.

Happy Birthday (a while back) !!!
It makes me so happy whenever these studies are done at CU Boulder. Sko buffs!
I feel you dude. You don't want your s.o. to waste money on something stupid and at the end it's frusttrating for both. Next time wish for something or accept whatever and feel happy that you made your s.o. happy. It helps.
In the mid 70s I was a radio maintenance technician in the USAF working in the HF radio maintenance shop. To check the operation of our radios we would tune to WWV, the NIST radio station which operated on 5, 10 and 15 megahertz sending out time hacks. It would a few seconds before the top of the minute it would announce that at the tone the time would be so-and-so Coordinated Universal Time. We would set our watches by WWV and so our watches were always really close to UTC. One evening my wife and I were at a Mall when a guy asked me what time it was. Whem I told him he said, "That can't be right!" to which I replied, "It is. I set my watch by WWV this morning." He then asked what WWV was and after I told him it was the official time for the U.S. he exclaimed, "What makes that right?". I was at a loss for words. How do you explain what makes the National Institute of Standards and Technology right? How would you have answered him? Anton? Anybody?
BTW I have clocks very similar to what you showed hanging in my kitchen and also in my man cave/computer room. I also have my PC set its clock with the NIST via an app. Plus I have a wrist watch made by Casio that sets itself from the NIST every 8 hours. I guess I like knowing the correct time. FYI, Anton, I think there is a version of that Casio watch that works in the Far East. It's called the "Waveceptor" and is available on Amazon. I love your videos. Keep up the great work!
In the US, AC power was made so any clock plugged into the wall would be right to within 3 seconds. Not 3 seconds / year. Just 3 seconds.
Basically, the old timely plug-in-the-wall clocks were as accurate as the atomic clocks. The problem happened when clocks started using the DC ("wall wart") power supplies. *Then* they needed the radios.
Nonsense, where did you hear that baloney. An electric clock will vary 2 to 20 minutes per year and some parts of our nation have more variations than others. Texas happens to be the bests since isolated. The atomic clock that are the reference for WWV stay within 100 ns of UTC and 20 ns of the national time standard, you can't say that about the 60 Hz mains frequency even within a day.
@@RWZiggy it is possible you've used poorly made clocks. There are specifications and companies with large motors won't damage them. I've never had to re-set one of those clocks.
TVs used the power grid for timing for decades.
This feels like a breakthrough waiting to happen. If the experiment can be successful in that it can measure accurately and be proven that it measured accurately, any result is a breakthrough. This is a question that even a yes or no answer would make theoretical physicists have a hayday, let alone the how of a yes or no. If they didn’t experience different time dilation, what dilation did they experience? If they did how does that work given they are the same particle? Really juicy info, makes me excited for the next few decades of theoretical physics. We had a barrier for so long where any measurement was impossible but the exponential improvement of measurement technology has provided new opportunities and will continue to provide new opportunities at a growing rate in the future. I feel like a great example of that improvement is how we got a picture of a black hole and that was a huge thing even though it was just a blur with a dark spot in the middle, and then just a few years later we have a picture of a black hole that includes the spiraling of the excretion disk.
Follow up question for Anton, or anyone smart.
Scenario in vid: The Yb atom is successfully placed in a superposition, then it's grabbed by a laser tweezer, then another laser tweezer is positioned near, which then grabs the same Yb atom at another point, because it's acting like a wave, kinda.
If I'm understanding correctly, when the superposition is "broken" both laser tweezers will have a Yb atom in them. The same atom, but now twice. Which is all well and good, but isn't that technically creation of matter? Or is the second atom not permanent? Or are we working with such small increments of time none of this matters cause quantum gonna quantum?
I feel like I'm missing something, maybe when the superposition is broken, there is only one atom again, or something relating to the observer effect?
Or at the end of the experiment there truly are two Yb atoms now and it's similar to how temporary/virtual(?) particles can borrow energy from the vacuum? The experiment itself can't be providing enough energy for creation of a Yb atom, unless it does because it's focused on such a small point, but I don't think this is the case.
What gives?
Breaking the superposition just leaves you with one trapped atom. The experiment would have to be conducted with the superposition intact, carefully measuring the small differences between the two locations without actually determining the 'true' location of the atom.
Great, thanks. That makes much more sense.
Side question, do you happen to know which trapped atom stays and which one disappears? After the superposition is broken. Disappears is the wrong word, but I think you follow what I mean.
If we designate them as Yb1 (the initial atom) and Yb2 (the newly captured superposition "version"), when the super position is broken is Yb1 always the one that remains? Or can Yb1 "leave" and Yb2 remains captured?
I see two possibilities. First, the time dilation might cause decoherence of the superposition. The particle emits a radio wave and chooses the lower position. Given the interaction with the tweezers, I think this is more likely. The second possibility is that the superposition holds the particle in a mean time frame about midway between the two separate places. For small time shifts, this is not at all unlikely; however, I expect that larger separations will favor the first choice even more -- the difference in energy (beat frequency) will soon happen quickly enough to radiate and decohere.
I rather feel like, we might get differening wavelength/frequency within the same wave function (of the particle). So, essentially, the particle will be in superposition of two different relativistic effect as well.
I think so by imagining what'll happen if a single wave of light is put in a gravity well. The wavelength will get red shifted closer to gravity, making a continous change in a single wave.
I hear ya, Anton. I find gifts to be confusing too
Thanks Anton.
Crystals can be shaped and tuned to do a lot of RF frequencies it's how radios work..
It's a common timer frequency crystal used in real time clocks :)
Nothings a gift beyond what you could expect
In 30 billion years spacetime will have stretched more than a second
A far more interesting experiment would be about the validity of entangled particles transferring their state to the other particles instantly.
If the "lower" particle is affected by time dilation more than the upper particle, that would dispell true quantum entanglement.
The entangled particles would be proven to have separate inertial reference frames and therefore couldn't transmit their state instantly to the other particle.
Yes, very interesting. There could be a slight delay observed in the lower particle materializing as spin up after the higher particle has already materialized as spin down.
@chriskennedy2846 yes exactly. I'm still pondering the implications of that in regards to the properties of entanglement.
It's differs substantially from experimenting with the superposition of a single particle as mentioned in the video.
I will also need to spend some time thinking about that experiments implications to quantum mechanics and times effect there, as normally "time" is somewhat glossed over in quantum mechanics.
Does "time" become a probability function in that experiment ???
Very interesting topic indeed !
@@John-ir2zf quantum nonlocality is a proven fact( if you rule out some interpretations) it is way faster than light at least, it should be instantaneous to make any sense.
You misunderstand entanglement. Nothing is transferred instantly. When one particle is observed, you instantly know the state of the other simply because it is always the opposite state. No data is exchanged. Nothing is changed about the unobserved particle.
@@samgragas8467 No, nothing is faster than light as light travels at the speed of causality.

With the birthday present, it's probably better to say thank you and pretend that you like it! It will still work as an ordinary (quartz) clock. Domestic relations are much harder than physics.
Whenever Anton is trying to connect to the audience ( smiling, talking in a joking manner, etc ) he's weirder than the lizard founder of Facebook and the video looks awkward like your friend is trying to tell a joke but he doesn't now how to deliver it
And I'm not even a hater, I've been watching since What the Math
Yeah, his face at the end of the videos going from completely stoic to instant fake smile is always funny to me.
I've got a radio clock in the UK and it works fine. I would assume if they were selling clocks in your country, they must be built to work with some signal local to you.
Wonderful as always Anton. Thank you. 🙂
10:23 & 10:30 I þink you mean "faster".
man I tell you these scientist is getting crazier by the day... measuring delta time of a same particle in super position with different gravity amount is something I don't expect to hear in my life time...
Amazing technology. I also read the paper.
