Study of Quantum Communication System with Coherent Light

Abstract:

In this paper， we introduced a system of coherent optical detection with homodyne， which implementing coherent optical communication，our own design based on the principle of coherent optical communication. IN the system, PCI6111E was useed as a data acquisition(DAQ) module. Alice and Bob’s control procedure by their computers under the LabVIEW. The synchronous detection and DAQ were carried out on the system. The signals were processed, displayed and measured. The Experimental results show that by light-synchronization and LabVIEW procedure control, each function module work together in cooperation, include Alice’s acousto-optic modulator and electro-optical modulator, Bob’s data acquisition and phase adjustment by PZT. The coherent optical information could be transitted by Alice and real-time demodulated by Bob.
