This blew my mind. The implications and functions a qbit could produce. Wow. We could run really accurate simulations or preform a million calculation a second with thousands or billions of parameters. Wow.
Silly question, when we say "complex" constants at 3:48, do you mean complex numbers? If so, how are real numbers insufficient for describing quantum states?
She does mean complex numbers. You definitely could also describe quantum states using Real numbers as well. You would simply represent a complex number of the form (a + bi) as an element of R x R, as they are equivalent as vector spaces. The use of complex numbers however lends itself to a more compact notation, as well has making some of the mathematics easier (arguably) to work with.
it will be possible to solve challenges regarding P versus NP about time usage in physical world. easier way to solve the problem is ignoring time and adjusting it as a field.
I think here's what I understood; Each additional electron in a molecule doubles the complexity of calculation for a binary computer, on the other hand each additional qubit sort of doubles simultaneous computational capability of a quantum computer, there for quantum computers should improve our ability to study molecular models beyond the capabilities of traditional computers.
resulting in finding better materials for every aspect of our lives, medicine and maybe even produce super conductive materials to build even more powerful quantum computers.
I'm still not really understanding the hardware. What does a cross-sectional TEM look like? How many terminals go into the device? Are there any passives or traditional transistors onboard the IC? What is an example of one line of code that can be executed?
I don't think they would give out the information about the hardware so easy. As for the language, I think it will be an abstraction of Python like others are doing.
@@sessilian Yes, our qubits are pretty much SQUID's connected to a capacitor (and in some cases an inductor too). You can look up "flux qubit" and "transmon qubit' for details.
I have an idea for a simulation I want to build in cirq but I barely know where to get started and my AI aren't multimodal enough to help yet. You guys have lots of hardcore fundamentals and extreme high level concepts but very little on experimental practical implementation. Need more videos on making useless things with quantum circuits.
I am very impressed by a so smart idea. If the quantum chip (you can hold into the palm of your hand) can truly simulate all the job performed by the big computer quantum artefact (with million of cables and connexions), so this big hardware is truly no more necessary to run a computer quantum. And also there is no more any risk of true atom manipulation. I am waiting for the next videos for more details. Thanks for sharing!
No one is asking how to make a quantum computer. What we want to know are what are it's current applications? How much is it being used in the market? What kind of problems is it currently solving? No one seems to answer any of these.
You guys should implement cirq into a Minecraft mod that has you building and programming your own redstone quantum computers. Not even joking, if you want young people to start learning this stuff as early as possible then gamifying it is the best way forward. You should already know this after the success of Ingress.
Isn't spin angular momentum the actual quantity used to represent the information rather than the electron levels? I mean we can work with electron levels but then we will have to treat entire atoms as our quantum objects because individual electrons don't have quantized energy states as such. And as far as I know(I am a CS undergrad, so I don't know much ), Hydrogen is the only candidate for such a quest, because we cannot even control the quantum properties of Helium as of now. And I don't think we will be using Hydrogen for this, owing to its other classical chemical properties. I don't know if there is a flaw in my direction of thinking? Please clarify. I also have read of a research where they manipulated entangled photons(for studying teleportation, as far as I remember). So, I think since they can be manipulated, they are also good quantum candidates. Please correct me if I am wrong. @googlers
Superconducting qubits, the devices we use at Google, are not individual atoms. They are macroscopic circuits, made of superconducting metal (usually aluminum). The quantum states are various levels of resonating voltage/current in the circuit. So as you can see, our quantum bits are not spin angular momentum.
I got a headache. There are lots of words I don't even know so if there are any video or course that can give me an idea about that please suggest me. I got a fever when I see the MIT's quantum computer courses' 1st video then I see double slit theory whole night I was only thinking "How? this is not how the world works.". So something for help.
No didn't notice one more thing, she is saying it a 5 min video. But it took 10+ mins to play on my traditional computer hardware. That's not how our world used to work :D
So well explained. Love the clarity of thought. But superposition and its usage still needs further simplification. Thank you Marissa
This was a great presentation. Google has made some incredible contributions to quantum computing. Thank you for sharing your work.
Wow Google hires really talented people, her voice is so professional so does the content 🙌
Perfect introductory explanation to dwell deeper and actually learn about the science.

Very good Marissa!
You put my brain in uncollapsible superposition state. :)
sounds very interesting, but now i even not really know how works regular bits - regular systems of electrons, thanks for video very inspiration✨
Great presentation! Very well explained considering the counter-intuitive subject of quantum mechanics. Nice quick lab tour.
Nicely explained. How do you code a quantum computer?

Each physical bit might be some sort of SQUID (Superconducting Quantum Interference Device)?
Check out the Microsoft Quantum Development Kit for more in depth examples ruclips.net/video/v7b4J2INq9c/видео.html
@@debjyotibiswas3793 Actually, there's a lot of publicly available published information about superconducting qubit design.

Probably I found my destination way! I choose this profession
Thank you for sharing this.
But I have a question, is using graphene a way to reduce the temperature? Or is this fake?
Where can I learn Quantum Mechanics online?

I know it is not the right place but can you give me information about the good online course about quantum computing?
If you already know some physics, I would personally recommend the book by Shankar.
OMG it's like this video is actually not in English at all ! So many Quantum English !
Are cognitive leaps the same as quantum leaps?
Interesting, thanks!
Loved it !
Thank you!

Love to work with quantum computers😍😍😍
Verry smart guys. This is verry efficient.

Skipped a little: “Well it looks like I don’t want to know what quantum computing is after all, interesting”
why these videos posted on TensorFlow's channel? I think, these videos need to post in their own channel, which videos are about quantum computing
D\_>mb sub racial human . Tensorflow is AU
So... Will we get to experience quantum computers? Or, are we already a part of quantum computing? Lol.
So an analog computer that applies the phenomena of quantum mechanics to simulate quantum mechanics.
Love the tshirt... ..:.:::.:.::...:.::...:.::.::::.:.:::.

The IBM thingy is more informative!

I'm too stupid for all this.
What?!
I believe that if you had a dog named ," Quanta" and it bit you, the pain would be exponential :-(
If you named him Qubit he would both kill a cat and not kill a cat at the same time and the cat would only be dead or alive when you looked.
So Marissa, 1 + 1 on your quantum computer is...? Really?
90% it is 2
9% it is 1
1% it is 0

why you putting quantumcast in the title, whyyyyyy
