Advancements Towards Long-Distance Quantum Communication

Prof. Chuanfeng Li and Prof. Zongquan Zhou from University of Science and Technology of China of the Chinese Academy of Sciences have realized noiseless photon echo protocol (NLPE). This new method reduced the noise by 670 times compared to previous methods. You can find the official publication of these findings below to read further.
