Physics Review Letters, an academic journal sponsored by the American Physical Society -- a US not-for-profit membership organization of professionals in physics and related disciplines -- published a research article by a research team from Institute of Opto-Electronics at Shanxi University (SXU) on Aug 14.

The article was written by Shi Shaoping, Tian Long, Wang Yajun, Zheng Yaohui, Xie Changde and Peng Kunchi.

It showcased the team's research results in the demonstration of channel multiplexing quantum communications, based on exploiting continuous-variable entanglement of optical modes.

Through decades of efforts, the Institute of Opto-Electronics at Shanxi University has developed synchronously with the international frontiers, prepared different types of squeezed and entangled state of light fields and completed a number of experimental studies into the fields of quantum communications, measurement and computing.

In recent years, the institute has been committed to transforming basic research results into applied technologies.

It has established a quantum technology research and development platform, which prepared a stable non-classical light field with a compression degree of up to 13.8 dB and an entanglement degree of up to 11.1 dB.

SXU officials said that made it one of the few laboratories in the world that can obtain a squeezed light field higher than 10 dB.
