Physicists React to 100,000 Qubit IBM Announcement 

I am a photon.

"you cant have a supercomputer in your pocket, the one i use is the size of a building" the cpu in our pockets today is multi magnitudes more powerful than the building sized computers of decades ago, give it time.

Really interesting. Subscribed. Hope to see other reaction/discussion like that. Would be nice to see a general but in-depth video about quantum computer. How they work, how is the answer obtained once the wave function collapse (do you have all the answer, only a part of it and need to rerun for the other part, etc?), whats the frequency of cslculation they can do, useful application beside cryptography , how computing power scale with the number of qbit, how error correction difficulty scale with the number of qbit, path of solution that are tried to solve error correction problem, how many real qbit = how many practical qbit (i think because of error you need a lot of physical qbit to have 1 effective qbit) , etc. Clearing out comon misconceptions, etc. Thanks!

Holy shit. From when are phisicists so fucking handsome. I'm jealous.

Actually a QPU makes perfect sense. In the same way that GPUs are good at certain tasks and not others - the same is true of quantum computers. So why not integrate both approaches - get the CPU and GPU to do their respective jobs running the OS, graphics, shuffling data to hard drives etc - then get the QPU to do any computations that specifically benefit from quantum computing.

News 📰 headline in 2033: "Physicists have created revolutionary 17-qubit quantum computer 💻"

It would be fun to see you guys discuss the differences between companies like IMBD, IONQ, Google and others quantum computers. Cheers 🤘🏼

I love how steam / Cyberpunk quantum computers look due to all the copper wiring and tubing lol. When William Gibson wrote neutomancer he believed that computers ran of crystals and quantum tech like we have now. When he finally got his first PC long after he wrote Neutomancer. He was super confused about the sound he was hearing. It was his floppy drive. Brought the PC back to complain about the sound. The guy explained how it worked and he was super disappointed since it was basically an advanced turn table he thought hahaha

Isn’t superposition where a particle is able to fit all parts of a specific wave function until it’s spin is observed thus revealing where it actually lies on that wave function? Additionally, entanglement is basically like if you and your friend were to agree on you paying for the night that you twi are hanging out, but you both never actually met and agreed, you both just knew you were going to pay no mater where or when you both are now or were before or will be later. Particles do that too but instead it has to do with different possible properties like the spin as I mentioned in my question.

general purpose qc, still 5-10yrs away, per uc berkeley news (jun/'23). results - lot of noise / error prone, need error correction s/w.

Curious how the idea of a personal computer with a QPU was tossed out as impossible immediately? You said "only super computers the size of houses use this type of tech". Maybe it's because I'm old, but supercomputers that were slower than your phone used to BE the size of houses lol and we very much carry them around now.

I think the entanglement description is a bit dangerous -- it's a great way to introduce it, but it does imply that the color of the balls is set prior, i.e. it uses local hidden variables.

Room temperature superconductor sounds like cold fusion.

Great explanation on superposition, another way to phrase it in "computer talk" for people who do not know. A regular computer works on bits to send information. 1 and 0's which classifies as (On or Off) on the circuit, kind of like normal electronics sending signals. Quantum Computing, which utilizes Superposition, can be all possibilities at one time, 1 or 0 or even both at the same time (On or Off).

Using quantum computers just seems like magic. Or is the superposition used to solve by creating an entire pattern that can be interpreted?

Entanglement example do9sound right. No internal states

9:55 the quote will be enshrined in infancy historians will look back on this as the same as the people said that cars and Automobiles was only a rich man's toy

First of all, the principal of superposition applies to all waves, not just to quantum waves. Overlapping waves combine, blending their undulations together by addition. The result, called a superposition, is just a point-by-point sum of individual waves that yields a new wave. All quantum particles can be described by quantum waves called wavefunctions. But these waves don’t represent the movements of physical things like water or air. Rather, their rolling peaks and valleys represent the probability that a quantum property like position or energy will have a certain value when it’s measured. The shape of this wave changes depending on the particle's energy. It’s possible to create a superposition in which two quantum waves---representing two particle energy levels---get added together, which leads to a new pattern of peaks and valleys. This changes where the particle is most likely to be found. In this kind of superposition, it’s common to say that the particle has two different energies at the same time, or that it’s in many places at once. This can be pretty confusing if you’re thinking of the particle as a classical particle, i.e., like a tiny hard ball. But if you imagine the particle as a wave, which is already an extended thing, superposition is a little easier to understand. Waves---including superpositions of quantum waves---are in many places at once. A quantum particle in a superposition, contrary to common belief, is not really in two (or more) states at once. Rather, a superposition means that there is more than one possible outcome of a measurement. For an object at everyday scales, described by classical physics, that makes no sense - it is either here or there, red or blue. If we can’t say which it is, that’s just because of our ignorance: We haven’t looked. But for quantum superpositions, there simply is no definite answer - the property of “position” is ill-defined. Technically, a quantum particle in a superposition is in a single superposition state, which can be represented as the linear combination of multiple basis states. The basis states are the wavefunctions for the possible outcomes of a measurement. Quantum superposition is fundamentally different from superposing classical waves. A quantum computer consisting of n qubits can exist in a superposition of 2^n states: from ∣000...0⟩ to |111...1⟩. In contrast, playing n musical sounds with all different frequencies, can only give a superposition of n frequencies. Adding classical waves scales linearly, whereas the superposition of quantum states is exponential. A pair or group of particles is entangled when the quantum state of each particle cannot be described independently of the quantum state of the other particle(s). The quantum state of the system as a whole can be described; it is in a definite state, although the parts of the system are not. In the paper Ludovico Lami, Guillaume Aubrun, Carlos Palazuelos, and Martin Plávala, "Entanglement and Superposition Are Equivalent Concepts in Any Physical Theory," Physical Review Letters (2022), the authors have shown that two physical theories exhibit entanglement when combined, if and only if they both exhibit local superpositions. This means that entanglement and superposition are equivalent in any physical theory, not just in quantum theory.

The guy on the left is a great singing vase.

I am IT and you are completely right! I don't run powerful AI on my home computer, I got servers for that! So obviously, we will have quantum servers to access!

I am working on light based computer which is faster than quantum computer theatrically now. But we can create it's size like a laptop. 12:53

Interesting on the quantum computer in a phone. I’m not one to say whether it’s possible or not but I don’t think the supercomputer analogy holds up. Supercomputers are just really really fast computers, to achieve those speed they, by definition have to be relatively huge. So it’s not *totally* inaccurate to say a supercomputer will never fit in your pocket (unless future computers get absolutely microscopic). But the power of a current-day supercomputer will almost assuredly fit in your pocket one day.

In fact, there is no entanglement with respect to wavelength (blue ball or red ball). Quantum Entanglement has been shown for spin, and that is it.

Why do u need more qbits when u can just superposition it all?

Why is the video bugging out?

My father works Alcoa aluminum he attended a luncheon being hosted by Mr Watson's son this is the fall of 1954 at that luncheon Watson Jr pointed out that in 10 years thanks to IBM's computer advancements every office would be paperless my father died at 96 and one of the last things he asked me a few years ago was James is your office paperless. The thing about technology it makes lots of promises the only promise I want technology to keep is the one that it will work occasionally and make life occasionally better for everyone after that everything else is just icing on the cake.

For a basic example: Imagine a password that is 100 characters long. In a standard computer, you have to brute-force, using iteration (one after another) until you find that correct one. That would take longer than the universe has existed (if that password was truly random). With a quantum computer, it does all the possibilities (up to 2^[number of qubits]) with a single iteration (all at once)... hypothetically.

You can just stream the quantum computer to your phone . Like I can stream my gaming pc to my phone and play high end video games on a crappy phone . We have nearly perfected low latency streaming . In the future scientists might all be streaming a google quantum supercomputer to a VR headset

Damn bro, this man making me act up

What's the name of the other physician???

The answer to the first question: Shor's algorithm. Quantum computers don't need entanglement, do they? Only the superposition of all states of the wave function of a subatomic particle.

IBM is a pillar in the US stock market and as a publicly traded company, can not be "throwing goals" into the cosmos without there being some substance or realistic probabilities in reaching that goal.

I read somewhere, for it to be really usefull, you would need at least 1 mio. Qubits. It looks like it will take us multiple decades until we will really benefit from a quantum computer

Have they actually found applications for quantum computers that don't involve breaking encryption?

First! Also, can moores law be applied to attempt to predict quantum computers? Can it be applied to them?

Optical computing is what I think is a missing link towards quantum computing.

"Superposition is easier to explain than entanglement" *proceeds to talk gibberish*

pop goes the bubble

“I think there is a world market for maybe five computers.” -- IBM in 1943. iPhone launched in 2007. ChatGPT launched in 2022. Room temp QPUs and Nuclear Fusion seem impossible now, but when they are invented -- it doesn't take long for humans to scale it.

Phones can work off the cloud tapping into quantum computing.

I feel like it would be way easier to get a working useful quantum computer if it was built in space or on the bottom of the ocean. I'm talking about lower temperatures and less noise

next time increase the volume

Leapfrogging towards quantum advantage :)

Gee..wonder what's gonna happen when they unleash a GPT4 type AI into this IBM Q comp...

wow these are totally real physicists guyz

This is an off topic, just thinking, I can't wait for some kind of quantum mechanical solution to solve diabetes and obesity. There are so many approaches and theories, but quantum models will be able to interpret what is truly necessary and the most effective and safest way to go. Especially for safely metabolizing visceral fat.

Why not, instead of developing quantum computers, we develop quantum processors, basically CPUs that work in a much more advanced way? We basically are doing that kind of and calling them computers which is dumb, additionally, we aren’t necessicerily thinking to the full capacity of this tech and are trying to do some kind of dumb stuff with what we think we already know everything about. It’s like if a caveman was to make fire and say that it is able to make light, this did actually happen I’m sure, and then never noticed that it makes heat and can cook meats and burn predators or other hostiles. We are the cavemen and the super “computers” are the fire, it does more than produce light.

In classical computing, GPUs typically have hundreds of bits and CPUs have 64 bits. However, when it comes to quantum chips, there can be many thousands of qubits. Why don't we see classical computers with 100k bits as we do with quantum chips?

Marketing. No one talks about error correction. No cloning principle applies to qubits.

What do you mean 100000 qubits? The IBM Quantum System One will be powered by the 127-qubit IBM Quantum Eagle processor.

I’m surprised this wasn’t already the goal. I always though quantum computers were just solvers (You give them a model for a problem, and it solves it).

Quantum biology (photosynthesis, human smell) takes place a room temperature. Do researchers know how to why nature does not need to operate in supercooled conditions?

Only the survivors will see the light

Sounds like shrodinger to me with the explanation at start of conversation

"Stock phrases of subduction events, related to the probability distribution of polarized sunglasses, tiptoe through the tulips with a rich heritage of pickle boats. Washed up on an uncharted desert isle during a three hour tour, the transistorized control system for unit sixteen creates a harmonious workplace environment for the perfect pizza party with the taste of real creamery butter. Rinse and repeat with free in-home consultations. Leaflets three, leave them be. This is the first successful unification of special relativity and quantum mechanics. According to the superposition principle of quantum mechanics, cognitive bias must hold residency for at least three-years to be able to have the tail wagging the dog, clean and bouncy and lemon-freshened. The gravitational lensing of the placebo effect of sensible shoes is naturally focused on aquatic therapy. Does this seem a bit ridiculous at first glance? I thought so too until I really started thinking about it. Quantum entanglement requires hot buttered popcorn to have steel resolve. Wearing plastic moose antlers will make you look like Bullwinkle." ---Albert Einstein

It’s vaporware. Vapor hardware.

You should first just let the announcementclip play through without interrupting it. THEN you can go back an comment all stuff that you “interrupting” the announcementclip with. But in the way you interrupt the announcementclip that “gets lost in translation”. I don’t even know/remember what the announcementclip is about cause you guys interrupt it constantly. Just let I play THE interpret it..

Sólo is intel chip

The announcement is GIGA-FLOP-SWEAT.

Quantum Noise is the greatest bane of Quantum Calculation. Having 2 or a million Qubits means nothing, if noise is not calculated and suppressed.

That entanglement explanation is so crap

Its a scam, what architecture are they pursuing? Saying quantum does not say a thing about the subject

100 000 qubit is such a marketing BS! The main goal should be entangling as many qubits as possible. There is no way they will achieve 100 000 fully entangled qubits. Having groups of fully entangled qubits can also be nice, but you should also know how big the groups are. For instance, 100 000 qubits entangled in pairs (50 000 x 2q) have smaller computing power than 64 qubits in 4 groups of 16 fully entangled qubits (4 x 16q).

Hey wouldn't like bubble gum get rid of ghe carbon or naw pike flying bubble gum drones something sticky and sugary

But...that's not entanglement! I'm at 1:52 in the video. I'm listening to the explanation of entanglement, and that is not the way it works! But maybe that's the just the first layer of explanation, and he's going to add more layers. Let's see. Ok, he did. He did do it right. Good! Okay, I've finished the video. It occurs to me that you could extend your explanation of entanglement by putting superposition into it. You want to emphasize that this is not classical physics. You want to point out that it's not a situation where there is a red ball in one container and a blue ball in the other. In one sense this is about what you know and what you don't know. But that's far from the whole story. The red ball is in both containers before you inspect one of the containers. It's superposed. It's in both places. It's not a question of you not knowing which container it is in; it is in both. And the universe only decides which container the red ball is in at the moment that you look to see. Before that point it is in both containers. Before looking the balls are superposed. They are in both places. And after you interact with one by looking in the box, both lose their superposition and become localized. Now I can guess, and say -- but I may be wrong because I don't know this for sure -- that the 100,000 Qbit computer would be the red ball/blue ball example extended to 100,000 pairs, except they are not independent. It would not be terribly useful to have 100,000 independent pairs. Instead it's all one big system so that if any box is opened, that will collapse the whole system of 100,000 Qbits. Every superposition is lost at that moment. And then the final pattern of red and blue localizations, all 100,000, is the answer somehow to a question being asked by the original pattern of superposition -- where some of the Qbit pairs were superposed and others were not. (Now I don't want to pretend I understand this. I don't. But I'm trying to reason through how it works.)

Im on God side guys. Dont open a door you cant close.

Blue+Red=Purple

Really! I have a chemistry & chemical engineering degrees and u trying to explain entanglement is a joke. I guess to try and trivialize this quantum computer’s innovation u want to also trivialize Schrödinger equation. I can’t wait to hear more jokes u have to say

Muy bien la reaccion pero estos se mastican la mandioca el uno al otro, altos trabas.

If graphene etc can t do - Place QUBITS in ISS - Musk will Can I subscribe ?

This sounds like something Satan would use, just saying, a form of omnipotence?

The answer is 42

AVP ?"library buddy / ,.. d worry / I deal with text additu all the time / we have to learn to deal with it

1:01 absolutely no offense but ChatGPT from 2021 could have produced a better/clearer explanation. You marketed yourselves as physicists. It's irresponsible to not properly formulate your thoughts before speaking, even if what you said is meant to be a truncated version. Again, no offense intended.

Hello world

IBM will run out of cash to invest in that far before 2033. It is so poorly run. I was a investor in IBM since 2008 thinking they would lead in AI as they were talking about smart cities and stuff like that but then i quickly reallise their big talk were always some small offshoot sprout without any revenue being generated and their exec real focus was always trying to catch up to AWS, and the like in the cloud or to try to preserve their business service segement from hp, dell and the like, around 2017 i saw that google had develop AI to spot certain Cancer on IRM scan and other small initiative, not much revenu their either, but i came to conclusion, that at the end of the last decades if i wanted to invest in AI the best bet where google and the like, so i ve drop IBM and just kept my investement in google, apple, microsoft, facebook without any change. Turn out i ve was quite rigth.

There are systems with coherent qubits that run almost as hot as room temperature already. People just aren’t allowed to talk about them. Public quantum mechanics is decades behind.

Rizzicists

Quantum Computing field, briefly: Talking a lot, saying very little, and making terrible analogies.

Yawn. Let me know when they actually accomplish something useful.

Misinfo

horrible explanation of quantum entanglement. Quantum entanglement is a phenomenon in which two or more particles become correlated, meaning that the state of one particle can affect the state of the other(s) even if the objects are separated by large distances. When two particles are entangled, their states are linked, and observations of one of the particles can automatically provide information about the other entangled particles, regardless of the distance between them. The quantum state of each particle of the group cannot be described independently of the state of the others, including when the particles are separated by a large distance Quantum superposition is a fundamental principle of quantum mechanics. In classical mechanics, things like position or momentum are always well-defined, but in quantum mechanics, a particle can be in a superposition of different states. Superposition explains how a quantum state can be represented as the sum of two or more states. When an electron is in superposition, its different states can be thought of as separate outcomes, each with a particular probability of being observed. For example, an electron might be said to be in a superposition of two different velocities or in two places at once.

Great scam

Useless video. No expert here, no real information about the topic here. Time wasted.
