The memory is operated with weak coherent pulses containing on average $1$ photons per pulse. The long-term stability of the memory efficiency and storage fidelity is demonstrated at the single-photon level together with operation in a non-laboratory environment.

• Abstract: We present the implementation and performance analysis of a portable, rack-mounted standalone warm vapor quantum memory system, that also includes the laser package, control electronics and data processing hardware. The optical memory is based on long-lived hyperfine ground states of Cesium which are connected to an excited state via the $D_1$ line at 895 nm in a $\Lambda$-configuration. The memory is operated with weak coherent pulses containing on average $<1$ photons per pulse. The long-term stability of the memory efficiency and storage fidelity is demonstrated at the single-photon level together with operation in a non-laboratory environment.

  We report on the high-efficiency storage and retrieval of weak coherent optical pulses and photonic qubits in a cavity solid-state quantum memory. We store weak coherent pulses at the single photon level with up to 62% efficiency for a pre-determined storage time of 2 $mu$s. We then store weak coherent time-bin qubits with (51+-2)% efficiency and a measurement-device limited fidelity over (94.8+-1.4)% for the retrieved qubits.
