200 seconds is only a brief moment, and 600 million years are already vicissitudes of life. On December 4, the China University of Science and Technology announced that the school’s Pan Jianwei and others had successfully built a “Nine Chapter” 76-photon quantum computing prototype. It only takes 200 seconds to solve the Bose Gaussian mathematical sampling algorithm, and the fastest super in the world.computerIt takes 600 million years. This advance made China the second country in the world to achieve “quantum superiority.”
“Quantum superiority is like a threshold, which means that when a new prototype of quantum computing, the computing power of a certain problem exceeds the strongest step.StatisticsComputers show that there are many possibilities to overcome in the future. “University of Science and Technology of ChinaprofessorLu Chaoyang said that over the years, the international academic community has paid great attention and is looking forward to this decisive milestone.
Last September, Googlethe companyHe entered 53 quantaLittle bitThe “Platanus” computer can calculate a mathematical algorithm in just 200 seconds, and the fastest in the worldsupercomputerIt took 2 days for the “peak” to reach “quantum superiority”.
Recently, Pan JianweiteamWith the Shanghai Institute of Microsystems, Chinese Academy of Sciences, NationalParallel computingmachineEngineering technologyThe research center cooperated and successfully built the “Nine Chapters” of 76 prototypes of photon quantum computing.
Experiments show that when solving the Gauss Bose sampling of 50 million samples, “Nine Chapters” takes 200 seconds, while the world’s fastest supercomputer “Fuyue” takes 600 million years. Equivalently, the calculation speed of “Nine Chapters” is 10 billion times faster than that of “Platanus”, and compensates for technical gaps in “Platanus” depending on the number of samples.
It is reported that the advancement of Pan Jianwei team has passed for 20 years.qualityThe three main technical problems of the photon source, high-precision phase lock and large-scale interference.
“For example, it is easy for us to drink one sip of water at a time, but it is very difficult to drink one molecule of water at a time,” said Pan Jianwei, the source of photons.WarrantyOnly one photon is emitted at a time, and each photon is exactly the same, which is quite a challenge. At the same time, the precision of phase lock should be within the minus ninth power of 10, and the transmission error equivalent to a distance of 100 kilometers cannot exceed the diameter of a hair.
Compared to general purpose computers, the “nine chapters” are just “individual champions.” But his superpower, in graph theory,Machine learning, Quantum chemistry and other fields have potential application value.
On December 4, the international academic journal “Science” published the result, and the reviewers rated it as “a more advanced experiment” and “a major achievement.”
