Abstract

A free space quantum communication multi-dimensional modulation system based on pulse position modulation and polarization encoding is put forward and designed and is used to send quantum information and classical information simultaneously. Atmospheric channel model and coexistence system model is built. We perform a simulation experiment for transmitting signal in atmospheric, using Optisystem and Matlab together. The binary sequence before modulation and that after demodulation are compared and analyzed. The error bit rate, eye diagram and quality factor of classical optical date are obtained. Stabilities of classical optical signal during the transmission are tested. The results show that this multi-dimensional modulation system can decrease the numbers of information channels needed and reduce the demands for power load and systematic complexity in communication terminals. The proposed quantum communication system is confirmed to be effective and applicable.
