With 113 detected photons, "Jiuzhang 2.0" can implement large-scale GBS septillion times faster than the world's fastest existing supercomputer.
Now that's quantum supremacy. Note the previous record holder for number of qubits was also Chinese, the Zuchongzhi at 66 qubits, achieve in July this year, implemented with superconducting qubit. Jiuzhang has achieved 113 qubit with photon. This also makes China the only country to achieve quantum computing with two different physical support. Zuchongzhi was about 10 million times faster than fastest supercomputer in terms of it's quantum supremacy.

Also, Jiuzhang 2.0's photons are programmable.

I gonna to rant. Even though I got no idea what I am talking about, I am still gonna rant!


1. The Western media will not report this. Just because!

Just because!!!


2. That original Chinese photonic computer was a work of art! I still cannot believe they lets us non-STEM noobs see a picture of it. That I truly appreciate the Communist Party of China of showing that picture. Awesome!

A photonic gun fires a single photon that is split, causing the entanglement to appear, in a superposition state (I think that is how it goes), those split photons go through that maze resembling a circuit board, going through crystals and they had the measuring instruments to actually see that photon. That is simply amazing!

The point is that thing was scalable. They just had to add another table top of that circuity stuff and they double the output. But, what they should do is improve the process, the crystals, instruments, etc., to improve output, ie the amount of qbits measured.

It is no surprise that they were able to have a version 2 so soon.


3. The original version 1 was programmable too. It probably was very rudimentary, not an expert here, but it was the experiment they did. The experiment keep on adding more variables, exponentially, something like that. You know what we call that? We call that a loop. So when does this loop end? When the if statement tells it to end. I am not a coder, but this is programming! If statements and loops! Now they say this version 2 is programmable. The semi-official story was version 1 was not. No way Jose!


4. What the hell is a loop? We can ask the coders here, has to be a couple on the forum. But, I will tell you what a loop is. A loop is a dictionary attack! Version 1 of Chinese quantum computer already capable of breaking any password in my opinion.


5. Bitcoin could be fraud. The quantum computer can do a loop. That's what they say in sports, speed kills.

:oops:

China is leading in future technologies development, and west is terrified about that :D
China will soon catch west on current tech, but west will never catch China in future tech, and they know that...
Obviously. China plans well for the future

China will ramp up investment in eight strategic emerging industries to foster new growth drivers, according to guidelines jointly issued by four government departments, including the National Development and Reform Commission (NDRC) and the Ministry of Science and Technology.
The eight strategic emerging industries are the new-generation information technology industry, bioindustry, high-end equipment manufacturing industry, new material industry, new energy industry, intelligent and new energy vehicle industry, energy conservation and environmental protection industry, and digital creative industry.

Quantum computers in lab environments is one thing, for actual practical use it's very different:

Despite their speed, these machines will not replace common computers any time soon. At this stage, they work only in a protected environment for short periods on highly specific tasks, and they make a lot of mistakes.

“In the next step we hope to achieve quantum error correction with four to five years of hard work,” said Pan, a professor with the University of Science and Technology of China in Hefei, in the southeastern province of Anhui.

“Based on the technology of quantum error correction, we can explore the use of some dedicated quantum computers or quantum simulators to solve some of the most important scientific questions with practical value,” he added.

So 4 to 5 years to any practical use and that's IF projections are correct.

Big HPC news. China has already broken the (true/LINPACK) exascale barrier in 2021—on more than one machine.
It seems they decided NOT to submit to Top500 due to political issues

That was not an hypersonic missile test.

And this supercomputer does not exist either, it is just 10 iMac computers in a room.

:p

I like the "NOT to submit to Top500". It is a move to discredit or downgrade the list. Instead, people in the world are forced to listen to two voices and make the choice of who to rely on. Build my own rival stage of show. In a way, up to today, people is like "this is that because somebody says so", in the future more question would follow "are you sure? because I heard something else."
