We demonstrated a new scheme for wavelength conversion of a single-photon wave packet for use in quantum information communication technologies. The scheme enables us to deterministically change the color and shape of a single-photon wave packet in a lossless manner. The scheme is directly applicable to single photons traveling in an optical fiber network and will be a key technology in developing a photonic wavelength interface for quantum networking.
