Quantum chaotic communication

The attack induced by the eavesdropper will lower the bit rate or even lead to the failure of quantum communication. To solve this problem, we introduce a so-called quantum chaotic communication method to mask and thus actively protect the quantum information by chaotic signal from being attacked. The encoding and decoding processes are realized by transmitting the communicated quantum signals through the auxiliary chaotic devices at both sides of the sender and receiver. The method is applied to two examples, in which continuous-variable coherent states and qubit states are successfully transmitted without being influenced by eavesdropping.
