China unveils 200-qubit dual-core quantum computer Hanyuan-2 but omits key performance metrics
China has unveiled a 200-qubit neutral-atom quantum computer called Hanyuan-2, claiming it is the world’s first to implement a dual-core quantum computing architecture. The system integrates two independently operating neutral-atom arrays in a single rack-sized unit, using rubidium-87 and rubidium-85 atoms. The company also highlighted installation and power features, saying it runs without complex cryogenic equipment and consumes less than 7 kW. Industry watchers note key benchmarks and peer-reviewed papers have not been released.

China develops all-iron flow battery electrolyte, claims 6,000 cycles and up to 80 times lower material cost
Researchers at the Chinese Academy of Sciences say they have developed an electrolyte for an all-iron flow battery that shows little performance degradation after more than 6,000 charge-discharge cycles. They argue raw materials could be up to 80 times cheaper than lithium-based batteries. The study focuses on improving long-term stability by reducing side reactions, active material loss and crossover. The work remains at the laboratory stage, with no pilot or commercialization timetable disclosed.

Chinese researchers develop 1,000 times faster process for wafer-scale 2D semiconductors
Chinese researchers have developed a process to grow wafer-scale two-dimensional semiconductors at about 1,000 times the previous speed, a report said. The team redesigned a chemical vapor deposition process and replaced a solid substrate with a liquid gold and tungsten bilayer to ease physical limits on growth speed. They produced a monolayer tungsten silicon nitride film and said the work suggests scalable manufacturing potential, though mass production, defects and cost remain obstacles.
