Fig. 1: Overview of the experiment.
From: Long-lived and multiplexed atom-photon entanglement interface with feed-forward-controlled readouts
a Experiment setup for the three-mode MQI (multiplexed quantum interface). PC: phase compensator (“Methods” section); CSMF: common single-mode fiber; OSN: optical switching network; QW: λ/4 wave-plate; BD: beam displacer, PBS: polarization-beam splitter; BTD: beam transformation device; SMF: single-mode fiber; OC: optical channel. BS1 (BS2): Non-polarizing beam splitter, whose reflectance (transmission) is 10% (90%). The write beam is aligned along the z-axis via BS1, and the read beam along the opposite direction to that of the write beam via BS2; AOM: acoustic-optic modulator; FC: fiber coupler; OSFS: optical-spectrum-filter set (“Methods” section). B0: bias magnetic field (4G). b Pattern of the array at the G-section. c Relevant atomic levels.
