Chinese scientists have achieved a lot of breakthroughs in various fields, such as quantum computing, astronomical observation, and brain-computer interface in 2023. Let's review some of the highlights.
1. Chinese scientists set new record in high-rate quantum key distribution
Chinese scientists have developed a high-speed quantum key distribution system to generate secret keys at a rate exceeding 110 Mb/s over a 10 km standard optical fiber, setting a new world record in the field.
The achievement is of great significance to the large-scale application of quantum communication and quantum network, according to Xu Feihu, a professor at the University of Science and Technology of China.
2. Chinese scientists develop first superionic hydride ion conductor at ambient conditions
Chinese scientists have developed the first superionic hydride ion conductor at ambient conditions, according to the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences.
With strong reducibility and high redox potential, the hydride ion (H-) is a reactive hydrogen species and an energy carrier. Materials that conduct pure H- at ambient conditions will be enablers of advanced clean energy storage and electrochemical conversion technologies.
3. China completes world's first brain-computer interface experiment on primate subject
China has successfully conducted the world's first brain-computer interface experiment on a non-human primate in Beijing.
The experiment successfully implemented a brain-computer interface in monkeys, allowing them to control a robotic arm with their thoughts. The experiment's success has positioned China as a front-runner in the technology.
4. Scientists grow human kidneys in pig embryos
A Chinese team has grown, for the first time in the world, kidneys from human stem cells inside pig embryos.
The advance that brings pig-grown human organs closer to reality will open an exciting avenue for
