Chaotic phenomena in quantum cellular neural networks

In this paper we consider coupled quantum-dot cells, which are usually used for quantum-dot cellular automata (QCA), as a build unit to construct an analog cellular neural network. It is also shown how simple connection of few quantum-dot cells (even two of them) can cause the onset of chaotic oscillation only with small differences of polarizations and template between cells. An example of polarization evolution in two adjacent cells is reported together with proof of their chaotic behavior.
