Quantum China Weekly

This week, in the business sector, Qasky and Minyu Digital completed a strategic cooperation agreement signing ceremony. Both parties will jointly promote the development and application of quantum technology in finance and other fields based on their respective technical and resource advantages.

In the direction of scientific research, CSU has been making progress this week. Scholars made important breakthroughs in the field of optical quantum storage, new progress in the field of optical non-reciprocal, cavity light force, and also discovered a new method for optimization of silicon-based spin quantum bit manipulation.

In terms of education, Tsinghua University’s Institute for Interdisciplinary Information Sciences will hold the “Summer Camp for Outstanding Undergraduates 2021” as one of the important ways to select talents for graduate students. 50 campers in physics and 100 campers in computer science are to be enrolled in this summer camp.

The CPS Fall Meeting is an annual academic conference sponsored by the Chinese Physical Society. The 2020/2021 Fall Meeting will be held on September 16-19, 2021 in Lanzhou, China.

CSU opens up new direction in non-reciprocal field to achieve 50dB noiseless all-optical isolation

The scholars at CSU have made new progress in the field of optical non-reciprocity, achieving 51.5dB of non-reciprocal isolation in the atomic system synthesis, which is the highest isolation ratio in the field of non-magnetic non-reciprocity, and for the first time explored the problem of quantum noise in non-reciprocal devices, proving that the new all-optical non-reciprocal effect does not introduce additional quantum noise.
