- Abstract: Quantum repeaters are indispensable tools for long-distance quantum
communication. However, frequency matching between entangled photon sources and
remote quantum memories (QMs) is difficult, which is an obstacle to the
implementation of quantum repeaters. In this paper, we demonstrate a method to
achieve the coupling of a Pr:YSO as a fixed-time QM with a single
telecommunication-wavelength photon through frequency stabilization using an
optical frequency comb over all applied laser wavelengths. The demonstrated
method can lead to the implementation of a quantum repeater scheme enabling an
improvement of the entanglement generation rate, paving the way for
long-distance quantum communication.
