Quantum frequency conversion of visible single photons from a quantum dot to a telecom band

Establishing a network of quantum systems will be based on single photons as flying qubits. For a long range transmission, wavelengths in the low-loss telecom bands will be necessary. As such a network may consist of dissimilar systems emitting at different wavelengths, an interface will be required converting the photons to the telecom band without disturbing the single photon quantum properties. We here demonstrate frequency down-conversion of single photons from a quantum dot and prove the preservation of the single photon character [1].
