Research
CSU boosts optical storage time to 1 hour
Scholars at CSU have made an important breakthrough in the field of optical quantum storage. The research team has improved the storage time of coherent light to 1 hour, substantially refreshing the world record of 1 minute of light storage by a German team in 2013, and taking an important step toward the realization of quantum USB flash drive.

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.
