Abstract: | In this paper the nonlinear dynamical behaviour of a quantum cellular neural network (QCNN)
by coupling Josephson circuits was investigated and it was shown that the
QCNN using only two of them can cause the onset of chaotic oscillation. The
theoretical analysis and simulation for the two Josephson-circuits-coupled
QCNN have been done by using the amplitude and phase as state variables. The
complex chaotic behaviours can be observed and then proved by calculating
Lyapunov exponents. The study provides valuable information about QCNNs for
future application in high-parallel signal processing and novel chaotic
generators. |
