Quantum Communication between Multiplexed Atomic Quantum Memories

Autor: Li, Chang, Jiang, Nan, Wu, Yukai, Chang, Wei, Pu, Yunfei, Zhang, Sheng, Duan, Luming

Publikováno v: Phys. Rev. Lett. 124, 240504 (2020)

The use of multiplexed atomic quantum memories (MAQM) can significantly enhance the efficiency to establish entanglement in a quantum network. In the previous experiments, individual elements of a quantum network, such as the generation, storage and
