Quantum cometh

wow if it's real

Google’s quantum computer was reportedly able to solve a calculation — proving the randomness of numbers produced by a random number generator — in 3 minutes and 20 seconds that would take the world’s fastest traditional supercomputer, Summit, around 10,000 years. This effectively means that the calculation cannot be performed by a traditional computer, making Google the first to demonstrate quantum supremacy.

Premature ejaculation, Macdoc.

The thread of comments is roundly entertaining. The report was pulled, if you only read a little of the main article, so what you're wow-ing about is third- or fourth-hand information by the time it gets to your favorite news feed.

Besides (from the third paragraph), "Despite hitting the milestone, it’s likely that quantum computers capable of tackling practical tasks are still years away."

Journalists frequently use that line when writing about quantum computing. We already knew when to shut this guy off.

Come to that, what's a practical task that a quantum computer is likely years away from tackling? That's some hard-hitting journalism, right there.

I'm starting to wish Fifth Ape would make a comeback.

Can't get over yourself can you cito?? - not even a clear caveat deters your puerile behaviour. :coffee:

You posted this thread to get some attention, not to provide anyone with any information You want attention, but don't know how to get the kind of attention you want.

At least you finally shut up about the fucking carbon credits. What happened? Did that Thunberg girl cross her legs...

across your typing finger?

so puerile ....

The Quantum computing post was an interesting article in an area i'm casually interested
....if you don't like it ....well you know my exact words for that ....so now execute. :nono:

John Preskill's debut article for Quanta magazine is about the idea and meanings of the term "quantum supremacy" that he proposed in 2012.

The article concludes:

In the 2012 paper that introduced the term “quantum supremacy,” I wondered: “Is controlling large-scale quantum systems merely really, really hard, or is it ridiculously hard? In the former case we might succeed in building large-scale quantum computers after a few decades of very hard work. In the latter case we might not succeed for centuries, if ever.” The recent achievement by the Google team bolsters our confidence that quantum computing is merely really, really hard. If that’s true, a plethora of quantum technologies are likely to blossom in the decades ahead.

There is still a significant bit of science missing from quantum supremacy being established. Sure, at present (or very soon) we may have a practical quantum supremacy, but this does not signify a certainty that quantum machines actually are superior.

To prove actual quantum supremacy, you need to show that the best possible classical algorithm for some class of problems is worse than some quantum algorithm for the same class of problems. This problem still seems to be far off.

I doubt many complexity theorists doubt whether quantum algorithms are superior to classical algorithms for some problems, but true science is not done by half-arsed assertions that don't follow logically from the evidence.

What google have done might be like proving that a horse runs faster on a diet specifically tailored for a horse than a donkey runs uphill on a diet tailored for reindeer. However, it's also possible they've proven that a horse runs faster uphill on a diet specifically tailored for a horse than a donkey on steroids runs on a flat surface on a diet tailored for a donkey on steroids. Currently, we just don't know which!

If some really surprising things happen in complexity theory, we might even reach a point where we push the donkey to keep up with the horse.

The first public lecture since the announcement of quantum supremacy will take place on November 1st @ Caltech

Abstract:

The promise of quantum computers is that certain computational tasks might be executed exponentially faster on a quantum processor than on a classical processor. A fundamental challenge is to build a high-fidelity processor capable of running quantum algorithms in an exponentially large computational space. Here we report the use of a processor with programmable superconducting qubits to create quantum states on 53 qubits, corresponding to a computational state-space of dimension 2^53 (about 10^16). Measurements from repeated experiments sample the resulting probability distribution, which we verify using classical simulations. Our Sycamore processor takes about 200 seconds to sample one instance of a quantum circuit a million times—our benchmarks currently indicate that the equivalent task for a state-of-the-art classical supercomputer would take approximately 10,000 years. This dramatic increase in speed compared to all known classical algorithms is an experimental realization of quantum supremacy for this specific computational task, heralding a much-anticipated computing paradigm.
