Achieving Multifunctional solid state quantum memory[2018-08-25]
The team Li Chengfeng, Zhou Zongquan and others from CAS Key Lab of Quantum Informaiton develope multi-degree-of-freedom (DOF) multiplexed solid-state quantum memory and demonstrate photon pulse operation functions with time and frequency DOFs. The result was published on Nature Communication recently. The faithful storage and coherent manipulation of quantum states with matter-systems enable... -
