Quantum-CNN to Generate Nanoscale Chaotic oscillators

In this letter we consider coupled quantum-dot cells, which are usually used for Quantum-dots Cellular Automata (QCA), to build Cellular Nonlinear Networks. In particular, it is 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 polarizations evolution in two adjacent cells is reported where hyperchaotic behavior has been observed. The richness of dynamics of Quantum CNN with only few dots is also emphasized.
