Abstract:

A quantum memory based on an atomic ensemble can act as a high-performance interface between atom and light in a quantum network and is an important building block of the DLCZ quantum repeater protocol. In this talk, I will introduce our recent works including (1) implementing a 2D array of atomic ensemble quantum memories with 225 cells, (2) generation and verification of experimental entanglement between 25 memory cells, (3) store-in and read-out of several photonic qubits in arbitrary sequences, (4) extending the coherence time of an atomic ensemble quantum memory and telecommunication wavelength conversion in an atomic cloud.
