China News Service, August 27. According to the website of China Internet Network Information Center, on August 27, China Internet Network Information Center (CNNIC) released the 48th "Statistical Report on China's Internet Development Status" (hereinafter referred to as the "Report") .

The "Report" pointed out that my country has become the main source country for 6G patent applications.

At present, the number of global patent applications in the field of 6G communication technology exceeds 38,000, of which my country's patent applications account for 35% (more than 13,000, or about 15,800), ranking first in the world.

  The "Report" shows that in the first half of 2021, positive progress has been made in many areas of information industry technology.

  In the field of 6G communication technology, my country has become the main source country for 6G patent applications.

At present, the number of global patent applications in the field of 6G communication technology exceeds 38,000, of which my country's patent applications account for 35% (more than 13,000, or about 15,800), ranking first in the world.

  In the field of chip technology, in March 2021, an international team led by Chinese researchers announced the development of a new programmable optical quantum computing chip that can realize fully programmable dynamic simulation of multi-particle quantum walks; domestic 7nm chip trial production will be realized in April In June, the Chinese Academy of Sciences successfully designed a 14nm "Xiangshan" chip. In August, SMIC's FinFET7 process reached the monthly mass production level of 15,000 pieces, and the high-end chip field has achieved phased results.

  In the field of quantum technology, the "Report" stated that Tsinghua University has completed the highly efficient entanglement connection between two DLCZ quantum relay modules in an experiment for the first time, which is a key step in the realization of a practical quantum relay; research by the University of Science and Technology of China The team has made an important breakthrough in the field of optical quantum storage, increasing the optical storage time to 1 hour, which greatly refreshed the world record of 1 minute for optical storage of the German team in 2013, and has taken an important step towards the realization of a quantum USB disk. At the same time, the team achieved it for the first time. Multi-mode quantum relay realizes predictable quantum entanglement between two absorbing quantum memories, which opens a feasible direction for the development of quantum relay and lays the foundation for the construction of practical high-speed quantum networks.

  In the field of satellite Internet, the first satellite produced by my country’s first small satellite intelligent production line was off the assembly line, marking my country’s acquisition of satellite mass production capacity; at the same time, breakthroughs were made in the technical test of the low-orbit satellite constellation system, achieving the depth of the low-orbit satellite network and the ground 5G network Integration has taken a key step in the research of my country's world-wide network general technology.
