So skillfully laid out and explained so that lay folks like us can really appreciate the work y’all are doing and how Quantum Computers work and will become more ubiquitous…thank you Dr. Lanes 🙏🏿
The room size quantum computer reminds me of the room size (classical) computer of the 1940s and 1950s. So how will the quantum computer look like in 50 years or so? Also: The control panel looks like something out a spaceship from Star Wars 🙂
I don't think there will be any kind of advancement this time. The big task or hurdle for Quantum Computers is its environment and creating the environment and the computing parts into a portable computer is something really really difficult and even can be said to be impossible. But for portability we already have it. We can access ibm quantum computers and try it out virtually now itself but will be running in the lab and I think advancement in that field will sure come.
@@neolxxxv5882look on the brighter side. The shall be significant advancements in the size and scale. In this day and age nothing is impossible
Pocket quantum computers circa 2100!
How on earth and why was my reply deleted? I’m an optimist for the advancement of quantum computers and shall be the pioneer in that
the difference with 1940s is that at that time classical computers were immediately useful. these machines are utterly useless for anything practical. these are basically a lab equipment.
Aaaah the sweet sound of reliquifier and compressor in the background! After working in the labs with cryogenics for a while, quiet rooms become unsettling because you always feel that something is going wrong! Hopefully, I can join this lab soon.
it's also concerning when you accidentally hit a big red button with your elbow and all the noises mysteriously stop
@@qiskitOh oh! that silence is the calm before the storm! Because you just turned off the compressor with that one button, and the system starts to pressurize, and pop-off valves start to open up to release the pressure in 10-15 minutes if you do not turn on the compressors. (That can also cause ice-block formation in the reliquifier).
What is going on down here :).... from a quantum enthusiast. Who else is from Quantum explorers 2023 cohort?
Thankfully the big red button has a cover on it to avoid elbows hitting it. Was the croygen quench switch, also sounds an alarm when lifting the cover. There were two, generic yellow and black button for electrical system emergency stop and the big red quench button under a cover. Hitting the e stop causes stuff to need a reboot and limits equipment damage. The quench button will cause irreparable damage to the magnet and loss of over 100k in cryogens.
Short video with a great knowledge , thank you Olivia
Thx for showing the installations and explaining them in more detail. As a chemical engineer I understand very well the auxiliary systems, but to grasp exactly how the quantum computer works will take more time and effort from my part. Thank you again!
Here's a simplified story how the quantum computer works:
The actual computer is the simple chip at the bottom of the dilution refrigerator. The reason it's at the bottom is because the way a dilution refrigerator works, is it creates a lower and lower temperature at every stage, starting from room temperature at the top, to 50K (Kelvin) to 4K to ~0.7mK to 0.4mK at the bottom.The spiral thing you see in the middle of the fridge is the dilution unit, which mixes Helium 3 (the lighter Helium atom with 3 electrons) with Helium 4 (the heavier one with 4 electrons), and makes Helium 3 evaporate from the mix, causing loss of energy.
A dilution refrigerator has 3 integral parts: The gas handling system, the compressor(s) (up to 3 or up to 9 in case of KIDE) and the cryostat itself. Each depend on the other to function.
The extremely low temperatures are necessary because qubits don't necessarily want to remain stable at higher temperatures.
As stated in every other video about QCs - Qubits calculate 2 probabilities at once and make it possible to state things that may take 1000s of years to calculate linearly with 1s or 0s alone.
The wiring from the chip up through each stage is through superconductive materials.
The user interface for a quantum computer is still software a normal laptop. It will likely never replace normal computing, but will be an use of breaking encryption or solving very specific codes, if the breakthrough stage of usability is achieved.
At it's current stage, it uses massive amounts of electricity and makes a lot of sound. It would be hilarious if I saw someone having a personal one.
Wow, I am also working on these types of cryostats for my PhD along with ADR and He4 ones, this is so fascinating! ❤
Reading your comment makes me feel guilty. I have been so excited that a new invention is on its way that will make quantum computing redundant in 2024, but now I feel bad because your enthusiasm is so inspiring that it almost makes me want Quantum computers to become a thing.
Of course, now it makes sense why the computer seems to be hanging from the ceiling, because the cold is gathering below. Very well explained, thank you very much
the most clear explaination about quantum cpu ever watched. thank you
Wow, most in-depth video I've seen yet on the topic. Never knew that it was RF used to communicate with the chip, very cool, great vid.
Adding vector network analyzers to list of things to learn about that experts place special significance on or emphasize as important.
Really enjoyed this tour, felt casual and raw while still avoiding excessive oversimplification. Very rare to see on RUclips for this topic.
A VNA is basically Smith chart for matching RF.
Thank you for the tour. What an extremely fascinating place to work in.
It really is!
Hey Dr Lanes, great video! It appears that quantum computer labs run tests and analyze the quantum computer system outputs. These computers take up several rooms. Are they capable of doing any kind of basic computation yet? Also will quantum computers one day be the size of classic computers? Presently they seem to need a lot of different systems, just to get them to behave the way they do? It was interesting to see IBM using classic computers to read the quantum computer signal outputs! I would think that quantum computer languages would become a compatibility issue for classical computers to understand and have the processing power for? The science is really amazing.
very good Dr Lane, explanation, very didactic, I understood everything, and very nice to explain
Excellent job in explaining how a Quantum computer functions 😊
Very nice explanation, for a normal person, quantum computer is not less than a magic..😊
Amazing tour. Love how in quantum we feel the hardware layer.
Now I know why it looks like a chandelier. The plates are lids to fridge cans, cooling to 0.015 degrees above absolute zero. The tubes are wave guides. That got me checking elsewhere about how microwaves flow in the chip itself for lower noise interactions. Thanks.
💐💐💐💐💐 Thanks Dr. Olivia
Fantastic video. Very educational and interesting. I've started sharing it already!!!
Fascinating, and all the minds that have created this promising machine.
Dr. Olivia lanes looks so young to be such a well established doctor. I'm 49 years of age so to me, she looks like a little girl. So well spoken and intelligent young lady. A great role model to all young women in the world.
Thanks its the sunscreen.
Awesome... awesome Olivia Your efforts are respectable, which cannot be expressed in words. 🙏
Dr. Olivia, you know too much I think 👏
This is sick, I have to see this in person
Amazing 🤓😍
Finally an explanation in details... by a person who actually builds quantum computers ! : D
Dilution refrigeratirs work by diluting helium 3 with helium 4. The mixture spoils the superfluid state of helium 4 and allows for much cooler temperatures than simply evaporative cooling can afford. If you made optical analog components rather than microwave electric, you would not even need the extreme cooling as the coherence would be intrinsic as a result of the laser phase locking to the atoms chosen to make your array. It is theoretically possible to put everything but the IO stuff on a monolithic nitride chip as well..😮
Nice vidéo !
Merci
Do you make all these in-house?
Wow Amazing 👌 Its everything quantum since last many decades but I saw actual quantum hardware.
As compared to cern lab its pretty smaller though it goes beyond subatomic realms.
I have read somewhere that to achieve massive computing power cooling and energy requirement is so high that it can create black hole.
Thanks for sharing
Cold room temperature for qubits should have its space around it in order to avoid external interference , there's a lot of electronics around that emits perturbations
thanks Dr. Olivia for such great explanation
Really fascinating.
Are those blue wires optic cables?
Also the quantum chip itself while large, but it is comparable to modern consumer CPU die, but all other things combined or even by themselves to make it work are certainly not.
Those copper wires are absolutely stunning by the way.
Its just as if a computer engineer was excitedly giving a tour of a room sized computer back in the 1950s! I wonder what people 50 years now, wearing quantum computing devices on their wrist or fingers, think when they see this video...
These hardware tours are great and all, but show us the computer actually doing something!
Awesome video!
Why silly background music 😢😢
Nicely done!
great tour
Can a quantum computer go on the internet or does it just perform simulations? How does it input/output information? How is it feed the information? what human interface do you use to control it like is there a quantum keyboard and mouse? is it like a giant external processor that you can attach to a desktop/laptop?
It is more of a quantum processor. we send analog microwave signals to the qubits to either process information or control the qubits themselves, then the signal goes into cables inside the fridge and are sent through amplifiers so that they can be read by the devices mentioned. no, there are no keyboard and mouse. its all controlled via microwave sources that send specific signals.
In all honesty these devices will probably never come to the general public. They're very useful in solving problems that have many combinations but other than that classical computers are much better and faster at solving and performing step by step operations.
this reminds me of the first Computers and now we have a smartphone , god know whats gonna happen in another 30 years
Lets Go IBM! 💪🚀🦅
Well explained!
The 16 qubit processor: are the qubits are physical or logical? Thanks for sharing this, very informative.
physical.
From now on, let's call them QUMPUTERS. Much better than the tongue twister 'Quantum Computers'!
I would love to have one of these things in my basement running my house as it's "brain" lol. In some loud ass room lol
So cool. What's a potential future use case? My early education suggested that most of the interesting things you can do revolve around simple but fast factoring of primes? Are the use cases of the future all cryptographic? Can this scale to a computationally relevant size for common tasks? Im an idiot trying to learn.
It can’t do anything useful now and nobody knows when and if it can become useful. That’s the reality. Also, note that they delete any comments that are not hyping the tech. So this is a disappearing comment

Hi Olivia,
A question-
I'm 55 y/old IT engineer.
My expertise is primarily SQL database development.
I'm interested to move to Quantum development. I'm working on my knowledge towards this field.
Any advice, please?
Highly appreciate your advice.
so that can thing is just a stacked giant yeti bottle?
So cool!!!!!!!!!
We need ig reels
Good stuff!
Everything computing revolution starts with ibm
Nice fridge, now show me the app! Just like on Morello & team('s) lab EEVlog video. I want to see how far those digitize go for "computing", sorry 'quantum state computing'.
Energy consumption? Eco-friendly?
Hi, I'm a Computer Student currently doing Graduate Course in India. I want to work on Quantum Computing at IBM. Please tell me how I can do it.
Get your Ph.D then go apply, I doubt they have anyone who is not a doctoral student or post doc working on this research.
6:56 is it gold plated ?
great video.
Very informative 👏
how do those dilution fridges reach 15mK when liquid helium only cools to 4K?
once the fridge reaches a temp of 4K, we can compress the mixture of helium 3 and 4 so that it enters a superfluid state allowing it to further cool down. when completely cool the fridge can circulate the mixture for continuous operation.
Quantum computers beat classical computers in the looks department for sure.
Shouldn't the title say "Dr. Olivia Lanes"?
?
What material is used in the lowest level other than copper
stainless steel and superconductors
@@qiskit thank you for the fast reply
Actually I have an other question
Is the super conductor is made of niobium
we cant share the secret sauce there unfortunately!
I never heard of millikelvin before, how close is it to absolute zero ?
milli = 1/1000
That's 0.015 kelvin 😲 , that is absolute Cold
Wow! Thak you very much for this!
Thanks for showing us around the lab. It so awesome that i wish i had one😅I wonder how many rooms of quantum computers IBM has!?
Do my eyes deceive me or did I see plastic zip ties holding the cables together on the demo model?
This is one of the coolest things I have ever seen. 😐
Everything and nothing at the same time.
It becomes a something when measured by an external observer.
Hi
Feels kinda funny watching Qiskit videos in the same building that Qiskit videos are made lol.
👏🏾👏🏾👏🏾👏🏾
In sci-fi movie, they put human brain 🧠 at the center.
There is room for six of these units in Almaden, why is ther just one?
wow
You are using a Lenovo laptop , OMG why ?
So you are telling me she isnt Shelby church's sister?
..Energy consumption?
Yes
Nice explain 🎉🎉 reply me
5:47 They stole that design from the show Devs, right? Lame!
Tiny things are in a quantum lab
"Russian nesting doll" = Matryoshka doll.
Though I have the power of God. Others are humans. Because mind works the way it should. Or machines.
The word you're looking for, Dearie, is "button." Those two letters in the middle are T's, pronounced by touching your tongue to the back of your upper teeth. I know you can do it because you do it right all the time when it's not in the middle of the word.
Somehow you seem to have picked up the impression that sounding like a North of England thug -- some old plug who got his teeth knocked out fifty years ago -- is fashionable. It may be -- in some cheap-ass druggie rock joints.
It just may be... But?
In the computer industry? Not so much.
It's a Northeast accent. And dont call me "dearie".
Best comment ever 😂
👍
Hallo permision me only
To do research you don't need big buildings and insane budgets. What is needed is intelligence and will.
China is far ahead than USA in quantum tech and all future tech.
USA has nothing much to boast in this field. Except videos to glorify it like these.
There is a limit to how much a country can go with hired talent from foreign countries, while it's own indigenous people drinks booze and sleeps.
Not sure I like her nail polish.
Ya 2/10 🙄
At 4:35 the HEMT amplifier is kept at room temperature, I thought it should be thermalised with one of the temperature levels inside the cryostat eg at the 4K stage . Wouldnt this produce better signal since there are lesser thermal noise photons?
I think the amplifiers are in the dilution fridge and what you saw at 4:35 is only the controller box.
Correct this is just the voltage box for the HEMTs. They are kept at 4k like you said
still have a long way to go before quantum computing is available at scale and out of the lab. Room temp or even non supercooled quantum computing would be a big boost to the adoption and innovation of this type of computing.
Not true. Cooling is not a big problem for us.
