China Challenges Google and Builds World’s Most Powerful Quantum Computer

Quantum Computing Grows Spectacularly in Recent Years. Not Only Did China Join the Race, but It Recently Won Against Tech Giant Google, Designing the Most Powerful Quantum Computer in the World!

Two years ago, tech giant Google announced that it had achieved “quantum supremacy.” The Sycamore computer represented a significant leap forward in the world of quantum computing. However, Chinese researchers challenged the online services and software giant Google and announced that they had developed an even more powerful quantum computer.

More Powerful Than Google

A team from the Hefei University of Science and Technology (China) claims to have built a machine that surpasses Google’s quantum computer. The researchers also provided details in a publication on the arXiv platform on June 28, 2021. However, for now, it is a pre-publication, pending peer validation.

In 2019, Google introduced the Sycamore, a computer with a 54-qubit quantum processor. The latter performed a highly complex calculation in just 200 seconds. However, this was a problem that a conventional computer would take about 10,000 years to solve.

In their publication, Chinese scientists refer to Zuchongzhi, a processor with 66 qubits. However, it only used 56 qubits for a simulation that would be two to three times more complex than Google’s two years ago.

China’s Quantum Supremacy: Achieved Without Using All the Power of the Processor

According to authorities, the Zuchongzhi completed the simulation in just over an hour. However, the current most powerful supercomputer, Fugaku from the Riken Center for Computational Science (Japan), would take at least eight years to solve the same problem. For the team, this is a victory that demonstrates China’s supremacy in scientific research.

The prospects are also very interesting in quantum research, through the resolution of more complex problems. However, as mentioned above, it is a pre-publication and not a publication in a reputable scientific journal. Thus, the Chinese researchers will have to demonstrate the power of their Zuchongzhi under the observation of other scientists for validation purposes.

Finally, let’s remember that other researchers from the Hefei University of Science and Technology have already presented their champion: Jiuzhang (76 qubits). In their December 2020 publication in Science, scientists estimated that the processor of this computer was ten billion times more powerful than that of the Sycamore computer. The scientists argued that, if the two computers had not been designed to perform the same types of tasks, the greater computational speed in the case of Jiuzhang could be considered the most relevant indicator of progress.
