BEIJING, July 12 (Xinhua) -- The following is a summary of published science and technology news of China.

ROCKET LAUNCH

China on Wednesday successfully launched a new carrier rocket into space from the Jiuquan Satellite Launch Center in northwest China. The Zhuque-2 carrier rocket blasted off at 9:00 a.m. (Beijing Time) and completed the flight mission according to the procedure.

Developed by the Chinese rocket company LandSpace, the Zhuque-2 is the world's first rocket to be powered by liquid oxygen-methane fuel and successfully enter its planned orbit.

ARCTIC OCEAN EXPEDITION

Chinese scientists set off for the 13th Arctic Ocean scientific expedition on Wednesday aboard the Xuelong 2, the country's first domestically built polar icebreaker, departing from Shanghai.

The expedition, organized by the Ministry of Natural Resources, is intended to conduct investigations into the geology and geophysics of the mid-ocean ridge, as well as atmospheric, sea ice, marine and subsurface environmental surveys, and surveys of biomes and pollutants.

It will improve China's capabilities in the areas of Arctic Ocean environmental protection and marine pollution assessment, and will obtain key information and data needed for related research, such as mid-ocean ridge dynamics.

QUANTUM COMPUTING

China has achieved the country's first algorithm verification of communication network optimization based on a universal quantum computer, according to the Quantum Computing Engineering Research Center in east China's Anhui province.

China Mobile is currently in the stage of 5G operation and 6G research and development. Compared with 5G, 6G will face computing problems such as larger-scale business optimization, network optimization, signal processing and machine learning, bringing about great pressure to the classical computation and algorithms, said Cui Chunfeng, an official from the China Mobile Research Institution.

The tremendous computing power is the main characteristic of quantum computers. "We try to start from small-scale problems in some typical scenarios to evaluate and verify the application feasibility of quantum computing in communication networks, especially in 6G," Cui said. Enditem
