This technology is expected to significantly reduce the insertion loss of on-chip optical ports, greatly promoting the development of high-density optical interconnection and photonic chip technology.

 

 

3. Chinese Scientists Conquer Earth Moon Laser Ranging Technology

Luo Jun, academician of the CAS Member, said in an interview with the China Science Daily that the "Tianqin Program" laser ranging station of Sun Yat sen University successfully measured the echo signals of five groups of reflectors on the moon surface, and measured the most accurate distance between the earth and the moon in China, with the accuracy reaching the international advanced level. This means that Chinese scientists have conquered the Earth Moon Laser Ranging technology, making China the third country in the world to successfully measure all five mirrors.

 

4. A New Approach to the Preparation of High dimensional Quantum Entangled Light Sources

The research team and collaborators of the State Key Laboratory of Solid Microstructure Physics of Nanjing University have made a major breakthrough in the research of high-dimensional quantum entanglement light sources. Researchers have successfully prepared high-dimensional path entangled and multiphoton light sources by combining a superstructured lens array with nonlinear crystals, breaking through the technical bottlenecks and information encoding dimension limitations of existing quantum light sources. This is of great significance for the development of quantum information technology with higher information capacity and security.

 

5. New research reveals that black phosphorescence immunotherapy can enhance anti-tumor efficacy

Zhang Han, a professor at the Key Laboratory of 2D Materials of the Ministry of Education of Shenzhen University, and his collaborators have proposed a photoimmunotherapy based on black phosphorus materials. This therapy, combined with CD47 antibodies, enhances the anti-tumor immune response. Zhang Han stated that given the excellent biodegradability and photoimmune performance of black phosphorus, it will demonstrate great potential in biomedical applications and clinical transformation.

 

6. Chinese scientists have increased the sensitivity of microwave measurement by 1000 times

Professor Jia Suotang and Professor Xiao Liantuan from the Laser Spectroscopy Research Institute of Shanxi University led a team to achieve the first prototype of a Rydberg atomic microwave superheterodyne receiver internationally, greatly improving the detection sensitivity of microwave electric field strength. The microwave measurement sensitivity is 1000 times higher than the previous international best level, and the minimum detectable microwave field strength is 10000 times higher than the previous international best level. This research achievement has greatly promoted the development of precision measurement of microwave electric fields, and has important application value in fields such as national defense and security, microwave communication, quantum metrology, electronic information, etc.

 

7. Institute of Physics, Chinese Academy of Sciences and others proposed Dirac vortex topology optical cavity

The team and collaborators of Lu Ling, a researcher from Group L01, Key Laboratory of Photophysics, National Research Center for Condensed Matter Physics, Chinese Academy of Sciences/Institute of Physics of the Chinese Academy of Sciences, and others have theoretically proposed and experimentally confirmed a new topological photonic crystal microcavity - Dirac vortex cavity, which can not only support cavity modes with any degree of degeneracy, but also is the best single mode cavity with large area among known optical cavities. This topological cavity fills the gap in the design of mode selection cavities for semiconductor lasers, providing a new development direction for the next generation of high brightness single mode surface emitting devices that conforms to the historical laws of commercial lasers, and has potential positive significance for technologies such as LiDAR and laser processing.

 

8. China has developed a vehicle mounted optical frequency standard that can last no less than 2.4 billion years in one second

The Institute of Precision Measurement Science and Technology Innovation of the Chinese Academy of Sciences has successfully developed a 2.4 billion year on-board optical frequency standard with a time difference of one second. According to team experts, the optical frequency standard is a set of ultra-high precision instrument equipment used to achieve ultra-high precision time measurement. The ultra high precision measurement of time is an important technical support for technological innovation and national economic construction, and also a key technology field with fierce international competition. As an ultra-high precision instrument and equipment, the primary requirement for achieving the application of optical frequency standards is to achieve "portability". Therefore, the research and development of onboard optical frequency standards has significant practical significance.

 

9. Fastest! China's Quantum Computers Achieve Global Leadership in Computing Power

200 seconds is just a fleeting moment, 600 million years have already been a sea of change. On December 4th, the University of Science and Technology of China announced that Pan Jianwei and others had successfully constructed a quantum computing prototype with 76 photons, known as "Nine Chapters". The mathematical algorithm for solving Gaussian Bose sampling only took 200 seconds, while the world's fastest supercomputer currently takes 600 million years. This breakthrough has made China the second country in the world to achieve "quantum superiority".

 

10. Number "1217": Chang'e-5 returns home, I will record and live stream it

On the early morning of December 17th, the Chang'e-5 spacecraft carried lunar samples and safely landed in the designated area of Siziwang Banner, Inner Mongolia. When I returned, all its actions were under my control. I am an optoelectronic tracking and measuring equipment, numbered "1217". After leaving my mother, the research and development center team of Changchun Institute of Optics, Precision Mechanics and Physics, Chinese Academy of Sciences, I have lived in the landing site of Siziwang Banner for five years. My main task is to look up at the stars, observe the spacecraft, record every action when they launch and return, so that scientists can control the spacecraft performance and do a good job in the whole process scheduling. The Chang'e-5 spacecraft has returned and I have successfully completed my observation of it.
