International China overtakes US in quantum computing

[monster zero]

We all know innovation is what America goes on about, but China might be leading the next 100 years on that front as well. Does it scare you to think about a China that may eventually pass us tech wise?

Named Jiuzhang after an ancient Chinese mathematical text, the new quantum computer can perform a calculation in 200 seconds that would take more than half a billion years on the world’s fastest non-quantum, or classical, computer.

“My first impression was, ‘wow,’” says quantum physicist Fabio Sciarrino of Sapienza University of Rome.

Google’s device, called Sycamore, is based on tiny quantum bits made of superconducting materials, which conduct energy without resistance. In contrast, Jiuzhang consists of a complex array of optical devices that shuttle photons around. Those devices include light sources, hundreds of beam splitters, dozens of mirrors and 100 photon detectors.

Employing a process called boson sampling, Jiuzhang generates a distribution of numbers that is exceedingly difficult for a classical computer to replicate. Here’s how it works: Photons are first sent into a network of channels. There, each photon encounters a series of beam splitters, each of which sends the photon down two paths simultaneously, in what’s called a quantum superposition. Paths also merge together, and the repeated splitting and merging causes the photons to interfere with one another according to quantum rules.

Finally, the number of photons in each of the network’s output channels is measured at the end. When repeated many times, this process produces a distribution of numbers based on how many photons were found in each output.

If operated with large numbers of photons and many channels, the quantum computer will produce a distribution of numbers that is too complex for a classical computer to calculate. In the new experiment, up to 76 photons traversed a network of 100 channels. For one of the world’s most powerful classical computers, the Chinese supercomputer Sunway TaihuLight, predicting the results that the quantum computer would get for anything beyond about 40 photons was intractable.

While Google was the first to break the quantum supremacy barrier, the milestone is “not a single-shot achievement,” says study coauthor and quantum physicist Chao-Yang Lu of the University of Science and Technology of China in Hefei. “It’s a continuous competition between constantly improved quantum hardware and constantly improved classical simulation.” After Google’s quantum supremacy claim, for example, IBM proposed a type of calculation that might allow a supercomputer to perform the task Google’s computer completed, at least theoretically

Not surprised. 0 regulation lets them get away with advancing faster

China already surpassed west in tech in some areas. If you ever been to China, you will find yourself like in 18th century in the west. Because they apply tech much faster to real life use.

but hows their sjw record? what about diversity? affirmative action? gender neutral pronouns and bathroom?

 

[White Whale]

Don’t worry American politicians will make sure China overtakes U.S. in everything.

I wonder what DARPA is working on?

been there in 2012, 2013 and 2018. difference from 2013 to 2018 was astounding.
they are real cocky about it too. they see america as a has been power.

 

[Ornife]

It was a good run, America. We can all rest easy though in the knowledge that the wealthiest, most privileged individuals will temporarily benefit from Chinese hegemony.

Dude the people on this forum legitimately have CDS (China Derangement Syndrome) and need to chill out. China is powerful but it ain't the end of the world. Did anyone really expect America to be on top forever? As long as we try and provide a good living standard to our own people who cares what other countries do. China has yet to invade another country so until they do that I think everyone seriously needs to go outside and take a deep breath. I couldn't imagine living in constant fear like some of you do.

Let's steal their IP.

^^^This and the fact China isn't hindered by moral bullshit.



America had a problem with fucking Stem cells because of religion.......Stem cells lol.......



China doesn't care, they will experiment and do things that benefits them, they have nothing holding back progress.

Yeah they're super nationalist now. IT kinda sucks but Xi's leadership will do that. I left in 2018, kinda didn't see a future there at that point. I don't like being the enemy when I'm in a country of 1.4 billion. Sure life is on easy mode there but it wasn't worth never feeling included.

Tibet called; they said you're full of shit.

I see America the same way at this point tbh. Nothing in the new direction of Americas leadership seems set to change that. Most of the world recognizes, Americans haven't yet.

Americans won't realize it until about a decade into the shift. They think because of the American middle class they are superior. You're already seeing that gutted as we speak.

No one is living in fear, we just need to know that when our kids are 18 in 2040 they may think about moving to China.

 

[Thepaintbucket]

It was going to happen sooner or later. The Chinese government has been pushing science education for the last few decades. Meanwhile we are all crying about Twitter and how science isn't always right.

looks like it, sadly. from afar it looks different, american's don't have that option, since they are in the whole deal. but the world is moving on. i do a lot of traveling and you hardly see americans in asia and africa anymore. africa is full of chinese, indians, russians, euros. it will be very visible in about 20 years.

and education is key. america spends a shitload of time and resources on race grifters, pronoun technology and diversity administrators.
