Multiplexed Quantum Memory in Cold Rubidium Ensemble

POSTER

Abstract

Atomic internal states in the ground-state manifold provide an ideal candidate for realization of quantum memory. Quantum interface links stationary qubits in quantum memory with flying photonic qubits in optical transmission channels and constitutes a critical element for future quantum internet. We use crossed acoustic optical deflectors (AODs) to realize a 2D multiplexed random access quantum memory via Duan-Lukin-Cirac-Zoller (DLCZ) scheme and electromagnetically induced transparency (EIT) effect. And further we generate multipartite entanglement between 25 (up to 100) individually addressable quantum interfaces in a multiplexed atomic quantum memory array.
