  • Multiplexing of quantum memories could boost the efficiency of photon state preparation. Here, the authors use a cold atomic ensemble and a single-photon resolving camera to exploit emission multiplexing of Raman photons from 665 different angular modes, confirming nonclassical photon-number correlations.

  • Quantum communications and distributed quantum computing can only be realized by efficient and robust entanglement generation between the communicating parties. The authors present and experimental demonstration of a wavevector multiplexed quantum memory from which Bell-type states are deterministically generated and have potential for use with quantum repeaters.

  • Continuous-wave conversion of a 13.9 GHz field to a near-infrared optical signal is demonstrated by using Rydberg atoms at room temperature. The conversion bandwidth is 16 MHz and the conversion dynamic range is 57 dB, descending down to 3.8 K noise-equivalent temperature.
