Single-photon-level memory at room temperature

Abstract

Quantum memories capable of storing single photons are essential building blocks for quantum information processing, enabling the storage and transfer of quantum information over long distances [1]. Devices operating at room temperature can be deployed on a large scale and integrated into existing photonic networks, but so far warm quantum memories have been susceptible to noise at the single photon level [2]. Using a fundamentally different approach to quantum memories, i.e. the recently developed far off-resonant Raman memory scheme [3], we present a highly efficient room-temperature memory that is able to operate with a low unconditional noise floor in the quantum regime, something that no other room-temperature memory has been able to demonstrate before. The quantum memory is operated in warm caesium vapour, and the long-lived, 9.2 GHz hyperfine-split states of the caesium D2 line serve as ground and storage states. The laser fields are 15 GHz detuned from the excited state.
