Quantum network with a current telecom photonic infrastructure is deficientin quantum storages that keep arbitrary quantum state in sufficient timeduration for a long-distance quantum communication with quantum repeateralgorithms. Atomic quantum storages have achieved subsecond storage timecorresponding to 1000 km transmission time for a telecom photon through aquantum repeater algorithm. However, the telecom photon is not directlyaccessible to typical atomic storages. Solid state quantum frequencyconversions fill this wavelength gap and add more abilities, for example, afrequency multiplex. Here we report on the experimental demonstration of apolarization-insensitive solid-state quantum frequency conversion to a telecomphoton from a short-wavelength photon entangled with an atomic ensemble.Atom-photon entanglement has been generated with a Rb atomic ensemble and thephoton has been translated to telecom range while retaining the entanglement byour nonlinear-crystal-based frequency converter in a Sagnac interferometer.
