摘要

The storage of a signal of a single-photon source based on spontaneous parametric down-conversion in a periodically poled MgO:PPLN crystal in a quantum memory based on an atomic frequency comb in an isotopically pure \(^{{{\text{143}}}}{\text{Nd}}{\kern 1pt} {\text{:}}{\kern 1pt} {{{\text{Y}}}^{{\text{7}}}}{\text{Li}}{{{\text{F}}}_{{\text{4}}}}\) crystal has been demonstrated.
