With Zuchongzhi, China has (again) reached quantitative supremacy

Thanks to the Zuchongzhi quantum computer, a well-known team of Chinese researchers has achieved remarkable results in preliminary work. He promised new advances in quantum computing.

at Pre-publish Impressively, Chinese researchers have just unveiled a new 66 qbit quantum supercomputer that represents a small revolution. The designers of Zuchongzhi — named after an ancient Chinese astronomer and mathematician — claim that he achieved quantum supremacy, a concept that means a machine is capable of performing tasks beyond the capacity of non-quantum supercomputers.

In the test, Zuchongzhi completed a benchmark designed specifically for quantum computers in just 70 minutes. According to the research team, a classic supercomputer would need about eight hours to do the same job. This allows researchers to claim that their devices have comfortably achieved quantum supremacy. It appears to be more straightforward and less ambiguous than its predecessors such as Google.

Our work unequivocally shows that we have achieved computational performance unattainable by classical computing in a reasonable amount of time., explains the research team.This high-resolution, programmable platform opens new doors for the exploration of many phenomena and the implementation of complex quantum algorithms.

Persuasive pre-study

Another advantage: Zuchongzhi’s architecture is fully expandable and scalable. When Jian Wei Pan and colleagues put him under an extremely heavy workload, they found that it always behaved exactly as expected, a critical component of the concrete applications of this technology.

On the other hand, it should be noted that this is only a file Pre-publish. Researchers still have to perform a large number of tests and prepare a robust research paper, which will be submitted for validation by other experts to validate the potential record.

But he is a very qualified team led by a world leader of quantum entanglement. His team has already excelled several times in this field, particularly in its work on a quantum computer. Jiuzhang. So we can be reasonably confident in their conclusions.

Analysis shared by physicist Peter Knight (who was not involved in the work). Asked new worldsays to himself,Very excitedwith these works. “This proves what we always thought we knew, but never succeeded in proving it empirically: we can always beat a classical machine by adding a few more qubits.”

A technological tour into a growing political sphere

Record or not, this is a major achievement on the part of Chinese researchers, in continuing their meteoric advances in high performance computing. Today, Beijing already has two of the world’s 10 most powerful supercomputers (Sunway TaihuLight and Tianhe-2A), but it doesn’t seem like it wants to stop there. And we understand it: By staying at the forefront of quantum computing, China is investing heavily in a technology that has the potential to become a new standard in the long run.

Even if some specialists doubt its practical applicability, quantum computing remains a research area of ​​major strategic importance. And not just for researchers and engineers. Because in the current geopolitical landscape, HPC – quantum or not – is beginning to become a primary metric, just as GDP, population or nuclear stockpiles are an expression of a nation’s strength. So it’s easy to understand why the research team can quickly boast of a result that has yet to be evaluated by their peers.
