Get your shit together Murica!
When a team of Chinese scientists beamed entangled photons from the nation’s Micius satellite to conduct the world’s first quantum-secured video call in 2017, experts declared that China had taken the lead in quantum communications. New research suggests that lead has extended to quantum computing as well.

In three preprint papers posted on arXiv.org last month, physicists at the University of Science and Technology of China (USTC) reported critical advances in both quantum communication and quantum computing. In one of the studies, researchers used nanometer-scale semiconductors called quantum dots to reliably transmit single photons—an essential resource for any quantum network—over 300 kilometers of fiber, well over 100 times farther than previous attempts. In another, scientists improved their photonic quantum computer from 76 detected photons to 113, a dramatic upgrade to its “quantum advantage,” or how much faster it is than classical computers at one specific task. The third paper introduced Zuchongzhi, made of 66 superconducting qubits, and performed a problem with 56 of them—a figure similar to the 53 qubits used in Google’s quantum computer Sycamore, which set a performance record in 2019.

I get that the published research puts them ahead but if Google did 53 qubits in 2019 and China did 56 in 2021, are they really ahead? Doesn't that presuppose that Google hasn't improved since 2019? Rather than they've improved but haven't published since then.

But that's a side topic. To me, the real story is how much China is funding this from the top down. Anyone have any idea how this compares with our National Quantum Initiative Act?
 
Why can't they make competitive processors with TSMC or Intel then? Why can't they even make me a decent dirt bike? Have you seen the prices of Yamahas or KTM these days? 11K for a 250 4 stroke. crazy.

China can tweak and improve, but for the time being the original ideas most always tend to start here.

The article's premise is hyperbolic, I think.
China's not ahead yet. But, there even being a conversation about it is indication of a trend that sees the US being quite likely left behind.

China'a a larger country, they've a smarter population, and they have actual long-term plans.
While they're not quite there yet, the odds are they're going to unseat the US from a lot of #1s.

This is a false assumption and should be updated. I wouldn't take it to the bank.

If Americans think that the Chinese can't innovate you're in for a rude surprise.

Other than some military applications, which I think the US will retain an extended advantage in (from a qualitative pov), everything else in the public domain is just a matter of engineering and resource. China has the money and the political will to overcome any supply chain restrictions - which is why we're seeing China throwing everything at semiconductors. By the by, I thought that was a monumentally stupid trade policy. US basically traded its strategic semiconductor industry to try and tank Huawei. Maybe the US values network control and standards over having control over semi-conductors. I don't know.

"not there yet" is not a good mindset given the chinese judge things in decades and sometimes centuries.
they're actually focused on the number 1 spot and they will get there without a doubt, in the next 10-20 years, which is nothing from the point of view of history.

Your computers are filled with Lizard eggs

Because they suck at top quality and anything refinied they rely on stealing.

China does make processors competitive to Intel. AMD handed over their design to the Chinese a couple years ago for some cash.
Before that we had at least a 40% lead on compute vs what China had. Then AMD came along and gave away the lead.
 
China is effectively a technological satellite state of the West.
It has shown little ability to innovate, only renovate what it has been taught.
They owe almost their entire modern development to Western knowledge.

That said, fair play to them advancing some of these fields.
When we feel like showing them something new, we will. Until then they can keep renovating on some of our technology.

Lol at them being smarter. The copy depends on the original, they and we all know this.

Indeed I think China is a bit of a paper tiger but any threat to consume over 50% of discretionary spending is good enough for MIC. I'm old enough to remember when Islamists would take over the world and Russia before that and no body expected their collapse. China will be same deal just wait and watch. Once we put all our allies together (china has no allies just clients like burma and NK) we'll strangle them with boycotts and sanctions. The alliance is coalescing now.

Their people will feel pretty pissed being factory to the world and no reward for it but a busted economy , air you cant breath, water you can't drink, and let it out on CCP. CCP will collapse. I give it 10 years max.

The US depends a lot more from private investment then the public sector. That being said recent news says the US is far ahead in a few key an important areas.

1 lowering resource requirements not needing giant cooling setups.

2 error correction very important for data integrity.

3. Qbit stability an duration of life of qbit.

4 massive improvements in superconductivity closer to room temperature.

US spends 4 billion a year on research.

Centuries? Sorry, that's bullshit, the PRC itself has only existed for 72 years.

1. the chinese does not equate ccp. the general mentality of the chinese is transmuting over most of the leadership structures of the last millenium, the last of which is the ccp.
2. the current ccp diplomacy uses a lot of examples from 80 or even 200 years ago to start off a lot of their presentations on current foreign policy. america cannot understand that because america is younger than a lot of the new items in the chinese national history museum.

This is wishful thinking.

China is not like the soviet union. It is the nearest thing to a peer competitor that the US has ever faced. It has an economy that is catching up and will overtake the US - something that's never happened before.

I do think the US is doing its best to strangle China in the cot, but I don't think it'll succeed. Once China becomes the biggest economy it will have allies because of its trading relationships, and it'll be the better option i.e. it could conceivably go with China instead of the US. Once we reach that inflection point we'll see a bifurcated world. I think now is only the start. At the moment the US still holds many advantages over China. But once China makes a few key breakthroughs i.e. develops its own capital markets and financial system that's not reliant on the dollar, breaks the semiconductor bottleneck and a few other things, it will be able to act with much greater independence. We're already seeing that trend with China discouraging Chinese firms listing in the US, the introduction of their own digital currency and new financial messaging system, and their Manhattan project like funding of the semiconductor supply chain. It's all coming.

There is also the problem of their best best scientists defecting to the United States. For some reason, this backwater country still attracts the best of the best from all over the world.
