A hybrid interface of solid-state single-photon sources and atomic quantum memories is a long sought-after goal in photonic technologies. Here, we demonstrate deterministic storage retrieval light from semiconductor dot an ensemble memory at telecommunications wavelengths. We store single photons indium arsenide high-bandwidth rubidium vapor–based memory, with total internal efficiency (12.9 ± 0.4)%. The signal-to-noise ratio the retrieved field 18.2 0.6, limited only by detector dark counts.
