Chinese scientists successfully developed a programmable superconducting quantum computing prototype "Zuchongzhi"

A research team composed of Pan Jianwei, Zhu Xiaobo, and Peng Chengzhi from the Institute of Quantum Information and Quantum Science and Technology Innovation of the Chinese Academy of Sciences of the University of Science and Technology of China successfully developed a 62-bit programmable superconducting quantum computing prototype "Zuchongzhi", and realized programmable Two-dimensional quantum walk. Related research results will be published online in the international academic journal "Science" on May 7, 2021.

This achievement lays a technical foundation for the realization of quantum superiority display on superconducting quantum systems and quantum computing research that can solve problems of great practical value. In addition, the two-dimensional programmable quantum walk based on the "Zuchongzhi" quantum computing prototype has potential applications in quantum search algorithms, general quantum computing and other fields, and will be an important direction for subsequent development.

Routers are sold out, routers suffer from shortage

Recently, a reporter asked multiple e-commerce platforms to learn that thanks to the increase in demand for Internet access such as remote office and online entertainment, router sales have been growing since the epidemic last year. At present, a few brands are experiencing tight supply, and the intensity and frequency of platform promotions have been significantly reduced. Some brand owners have expressed that they are preparing for possible shortages in the future. According to industry insiders, “the amount of network communication exchanges that were originally expected to be reached in the next three to five years seems to have exploded in an instant.”

Usually, the chip is the largest cost component of a router. The reporter visited a number of local Netcom product manufacturers in Kunshan and learned that the recent increase in raw material prices has reduced the profitability of the company. Kunshan Customs told reporters that the concentration of local electronic product companies has a large demand for chips, and the shortage of chips has appeared since the second quarter of last year. Whether it is automotive, consumer electronics, or network communications, chip supply is generally tight.
