High-Capacity Atom-Photon Interfaces for Quantum Information
Abstract
Atom-photon quantum interfaces with entangled photons can enable unconditionally secure long-distance quantum communication (LDQC) by implementing quantum repeaters based on atomic ensembles to overcome the degradation of fidelity of quantum information over long distances. Moreover, the potential to encode an unbounded amount of information in the orbital angular momentum (OAM) of single photons could potentially enable LDQC with high capacity. We propose to demonstrate the physical systems which are fundamental building blocks for these high-capacity LDQC technologies based on OAM: a source of entangled photons carrying OAM in high dimensions compatible with atomic quantum memories; and a multimode atomic memory to store single photons with high-order OAM. We will use warm ensembles of Cesium atoms to generate entangled photons carrying OAM using a four-wave mixing process and to store single photons in high-dimensional spaces, and we will investigate the requirements for interfacing entangled photons in high dimensions and multimode quantum memories for enabling high-capacity LDQC technologies.
