Quantum correlations between long lived quantum memories and telecom photonsthat can propagate with low loss in optical fibers are an essential resourcefor the realization of large scale quantum information networks. Significantprogress has been realized in this direction with atomic and solid statesystems. Here, we demonstrate quantum correlations between a telecom photon anda multimode on-demand solid state quantum memory. This is achieved by mapping acorrelated single photon onto a spin collective excitation in aPr$^{3+}$:Y$_2$SiO$_5$ crystal for a controllable time. The stored singlephotons are generated by cavity enhanced spontaneous parametric down conversion(SPDC) and heralded by their partner photons at telecom wavelength. Theseresults represent the first demonstration of a multimode on-demand solid statequantum memory for external quantum states of light. They provide an importantresource for quantum repeaters and pave the way for the implementation ofquantum information networks with distant solid-state quantum nodes.
