Researchers in China have developed a Quantum processing unit (QPU) that is faster than 1 quadeline (10⁵) fold The best supercomputers on the planet.
New Prototype 105-Cobot Chip, called “Zuchongzi 3.0”, which uses Super Conducting CoabsAhead represents a significant step Quantum computingScientists at the University of Science and Technology of China (USTC) in Haifi said.
This is a rival to the results of benchmarking founded by Google’s latest Willow QPU In December 2024, who allowed scientists to claim Quantum supremacy -Where quantum computers are more capable of high-speed supercomputers-in Lab-based bench marking.
Scientists used a processor to complete a task on widely used quantum computing Random circuit Samples (RSC) benchmark in just a few hundred seconds, in a new study published in the journal March 3. Physical review posts.
This test, taking 83 coats, random circuit samples of 32 layers, also completed 1 million times faster than Google’s previous generation results compiled by psychiatry chipPublished in October 2024. FrontierThe world’s second fastest supercomputer, on the contrary, can complete only one task in 5.9 billion years.

Although the results suggest that QPUs are capable of achieving quantum supremacy, specific RCS benchmarking used supporters of quantum methods. Also, the improvement in the classic algorithm that runs the classic computing can shut down the gap, as happened in 2019 when Google Scientists First announced that a quantum computer has improved the classic computer – In the first use of the RSC benchmark.
Scientists said in the study, “Our job not only pushes the fronts of quantum computing, but also offers the basis of a new era where quantum processors play an essential role in tackling the challenges of the latest real world.”
To counter Google’s best quantum processor
The latest Zuchongzi repetition includes 105 transmission cubs, such as tantalum, nebum, and aluminum, which reduce the sensitivity of the noise-15 by-7 rectangular net. It contains the previous chip, which includes 66 causes.
The most important sector for quantum computing in real -world settings is the time of harmony in the most important sector, a measure that a Qibbat can maintain its super position and tap in the rules of rules. Quantum mechanics To calculate in parallel. Long harmony times mean more complex actions and calculations are possible.
Another major improvement gate was in the correction of loyalty and quantum error, which has been hindering the construction of useful quantum computers. The gate measures loyalty to the extent to which a quantum gate performs its desired operation properly, where a quantum gate is in accordance with the classic logic gate, which performs a specific operation on one or more quet, and manipulates them in a quantum state. Highly sincere quaties mean less errors and more accurate counts.
Zuchong’s 3.0 performed with an impressive parallel single -gate loyalty, and 99.62 % parallel two coat gates loyalty. Google’s Willo QPU brought it slightly, respectively, with 99.97 % and 99.86 %, respectively.
Scientists said in the study that this improvement was largely possible due to the improvement of engineering, including increasing fabricated methods and designing better correctional cobs. For example, the latest repetition explains the cobbat ingredients using tantalum and aluminum, which is bound by the indometment of the Indem Bump Flip Chip process. This improves accuracy and minimize pollution.
