Application of entangled photons technique in secure communication

Secure communication is a ultimate target pursued by human being. However, all current methods of secure communication can eventually be broken by faster computing. The method based on entangled photons technique provides a powerful solution for totally secure communication. Because eavesdropping changes the physical nature of information, users in such communication system can easily detect eavesdroppers. We propose an entangled photons-based method and demonstrate in theoretical simulation, this method improves the performance of communication system.
