Secure Communication Based on Tracking Control of Quantum Cellular Neural Network

Based on the tracking control of chaotic system, the synchronization of hyperchaos in three-cell coupled quantum cellular neural network is studied; a secure communication system based on the hyperchaotic synchronization of the quantum cellular neural network is presented; its performance in the presence of channel noise is analyzed. Numerical simulations are given to illustrate the effectiveness of the hyperchaotic synchronization and secure communication. It is more secure due to the use of hyperchaos.
