Abstract
A multi-channel free-space optical wavelength division multiplexing system for optical quantum communication includes a transmitter configured to encode an input signal into a weak optical signal carrying quantum information, and to transmit the weak optical signal over a plurality of frequency channels in free space, each of the plurality of frequency channels corresponding to a plurality of photons of the weak optical signal, and a receiver configured to receive and decode the weak optical signal.
