High-Capacity, Single-Photon-Level Warm Atomic Memory Storing up to 120 Spatial Modes

Not Accessible

Your library or personal account may give you access

Abstract

We report first experimental demonstration of a warm atomic memory operating at a single-photon-level, capable to store and retrieve up to 120 spatial modes. We present unambiguous spatial g(2)(θS, θAS) cross-correlations between heralding and retrieved photons stored up to several microseconds.
