Following a recent upgrade, the USC-Lockheed Martin Quantum Computing Center (QCC) based at the USC Information Sciences Institute (ISI) is now the leader in quantum processing capacity.

With the upgrade — to 1,098 qubits from 512 — the D-Wave 2X™ processor is enabling QCC researchers to continue their efforts to close the gap between academic research in quantum computation and real-world critical problems.

The new processor will be used to study how and whether quantum effects can speed up the solution of tough optimization, machine learning and sampling problems. Machine-learning algorithms are widely used in artificial intelligence tasks.

Its fake and shear lies infect its fraud to mentioned quantum computer. There is nothing such stuff as quantum computer. All these QCs ideas r still ideas/imaginations/theoretical and no body even know how to materialise them. Actually the idea of quantum computer has been generated by some academics to fool the rich companies/countries to attract funds for research (intention was not to make them fool as they themselves were thinking its workable idea) .
In start it was not fraud even one can say subject of QC based on impossible idea but that idea helps well for academics in getting funds as many companies shows interest to spend in it.

PHYS771 Lecture 14: Skepticism of Quantum Computing

Scott Aaronson

Scribe: Chris Granade

Last time, we talked about whether quantum states should be thought of as exponentially long vectors, and I got challenged a bit about why I care about the class BQP/qpoly and concepts like quantum advice. Actually, I'd say that the main reason why I care is something I didn't even think to mention last time, which is that it relates whether we should expect quantum computing to be fundamentally possible or not. There are people, like Leonid Levin and Oded Goldreich, who just take it as obvious that quantum computing must be impossible. Part of their argument is that it's extravagant to imagine a world where describing the state of 200 particles takes more bits then there are particles in the universe. To them, this is a clear indication something is going to break down. So part of the reason that I like to study the power of quantum proofs and quantum advice is that it helps us answer the question of whether we really should think of a quantum state as encoding an exponential amount of information.

So, on to the Eleven Objections:

Works on paper, not in practice.
Violates Extended Church-Turing Thesis.
Not enough "real physics."
Small amplitudes are unphysical.
Exponentially large states are unphysical.
Quantum computers are just souped-up analog computers.
Quantum computers aren't like anything we've ever seen before.
Quantum mechanics is just an approximation to some deeper theory.
Decoherence will always be worse than the fault-tolerance threshold.
We don't need fault-tolerance for classical computers.
Errors aren't independent.
What I did is to write out every skeptical argument against the possibility of quantum computing that I could think of. We'll just go through them, and make commentary along the way. Let me just start by saying that my point of view has always been rather simple: it's entirely conceivable that quantum computing is impossible for some fundamental reason. If so, then that's by far the most exciting thing that could happen for us. That would be much more interesting than if quantum computing were possible, because it changes our understanding of physics. To have a quantum computer capable of factoring 10000-digit integers is the relatively boring outcome -- the outcome that we'd expect based on the theories we already have.

I like to engage skeptics for several reasons. First of all, because I like arguing. Secondly, often I find that the best way to come up with new results is to find someone who's saying something that seems clearly, manifestly wrong to me, and then try to think of counterarguments. Wrong people provide a fertile source of research ideas.

Why do Americans invent everything leaving nothing for the rest of us to discover?!!?!!?!?!

but you indian people called USA your father already isn't it, why still whining about?

Wow, you're rude. Funny how you guys talk so much online but in real life you guys can't even look people in the eyes.

Wow, you're rude. Funny how you guys talk so much online but in real life you guys can't even look people in the eyes.

We look down on you Indian, don't you see how you stupid billion people doesn't have a toilet.

Luke I'm your father, lol. Anyways I believe you have japanese genes in you, speaking of daddies

Indians contribute greatly to our GDP, chinese don't even come close and many abuse our welfare system.

Hahahaha lol you sound and act like an idiot.

Why do Americans invent everything leaving nothing for the rest of us to discover?!!?!!?!?!

Their massive economy coupled with being a developed nation allows them to invest a lot in R&D.

This is similar to Soviets who back in 70s were coming up with amazing stuff like this:

They can't even look at me in the eyes. They are afraid that I'm going to beat the living 5h1t out of them.

Look out, the Chinese are going to steal this technology too.
