Study of Secure Optical Communication based on Quantum Entanglement
Classical secure communication mainly has the following drawbacks.The first one is that we cant theoretically prove that the algorithm cant be broken.Then,with the rapid development of quantum computer,the algorithm can be cracked in a short time.In this paper,a new way of secure optical communication based on quantum entanglement is discussed.N-slit interferometry is used to generate a series of optical signals which represent some characters with specific meaning.Any intra-path perturbations will lead to the collapse of wave function.By using the Diracs notation,propagating interferograms can be predicted successfully which carry specific information.The results show that interferometric signal particularly suitable for optical communication.
