Single-Photon Storage in a Ground-State Vapor Cell Quantum Memory
Storing single photons from solid state sources in hot atomic vapor has been a long standing challenge due to read-out noise produced by the atoms. With a storage scheme exploiting polarization selection rules we have succeded in storing photons from a broadband pair source based on spontaneous parametric down conversion, as well as maintaining their single photon nature upon read out. These results have been published in PRX Quantum.
