Synchronization and multichannel secure communication of quantum cellular neural network

The synchronization of hyperchaos in three-cell coupled quantum cellular neural network is studied; a three-dimensional nonlinear controller is designed to make the controlled hyperchaotic system realize self synchronization and it´s proved by means of Lyapunov function that this method can make the system approach to any desired smooth orbit at an exponent rate. A multichannel secure communication system based on the hyperchaotic synchronization of the quantum cellular neural network is presented; numerical simulations are given to illustrate the effectiveness of the secure communication. It is more secure and economic due to the use of hyperchaos and multichannel communication.
