The realization of large-scale quantum networks—also known as quantum internet—will require quantum repeaters to enable quantum communication over distances much longer than the fiber attenuation length. The nodes of a quantum repeater are matter systems that should efficiently interact with quantum light, allow entanglement with photons (ideally at telecommunication wavelengths) and serve as a quantum memory allowing long-lived, faithful and multiplexed storage of entangled quantum bits.
