Noise suppression in a temporal-multimode quantum memory entangled with a photon via asymmetrical photon-collection channel

Ya Li, Ya-fei Wen, Min-jie Wang +5

Quantum interfaces (QIs) that generate entanglement between a multimode atomic memory and a photon forms a multiplexed repeater node and hold promise to greatly improve quantum rep…

Long-lived and multiplexed atom-photon entanglement interface with feed-forward-controlled readouts

Shengzhi Wang, Minjie Wang, Yafei Wen +4

The quantum interface (QI) that generates entanglement between photonic and spin-wave (atomic memory) qubits is a basic building block for quantum repeaters. Realizing ensemble-bas…

Deterministic generation and partial retrieval of a spin-wave excitation in an atomic ensemble

Shengzhi Wang, Zhongxiao Xu, Dengxin Wang +6

In this paper, we report a generation of a spin-wave excitation (SWE) with a near-unity () probability in a given time (~730). Such deterministic generation relies on a feedback sc…
