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 🙏🏿

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.

the most clear explaination about quantum cpu ever watched. thank you

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.

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.

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 KZread for this topic.

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.

very good Dr Lane, explanation, very didactic, I understood everything, and very nice to explain

Fantastic video. Very educational and interesting. I've started sharing it already!!!

Amazing tour. Love how in quantum we feel the hardware layer.

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.

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.

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.

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).

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.

Amazing 🤓😍 Finally an explanation in details... by a person who actually builds quantum computers ! : D

Awesome... awesome Olivia Your efforts are respectable, which cannot be expressed in words. 🙏

Fascinating, and all the minds that have created this promising machine.

Do you make all these in-house?

Nice vidéo ! Merci

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.

Awesome video!

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.

Dr. Olivia, you know too much I think 👏

Nicely done!

This is sick, I have to see this in person

great tour

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

Well explained!

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.

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

Energy consumption? Eco-friendly?

Wow! Thak you very much for this!

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.

how do those dilution fridges reach 15mK when liquid helium only cools to 4K?

@abdulmohamed9754

4 ай бұрын

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.

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..😮

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?

@abdulmohamed9754

4 ай бұрын

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.

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!?
