Quantum-dot Cellular Automata (QCA) has low power consumption and high density and regularity. QCA widely supports the new devices designed for nanotechnology. Application of QCA technology as an alternative method for CMOS technology on nano-scale shows a promising future. This paper presents successful designing, layout and analysis of Multiplexer with a new structure in QCA technique. In thi...

A classical local cellular automaton can describe an interacting quantum field theory for fermions. We construct a simple particular version of the Thirring model with imaginary coupling. This fermionic obeys unitary time evolution and shows all properties mechanics. Classical automata probabilistic initial conditions admit description in formalism Our exhibits interesting features as spontaneo...

We study matrix product unitary operators (MPUs) for fermionic one-dimensional (1D) chains. In stark contrast with the case of 1D qudit systems, we show that (i) MPUs do not necessarily feature a strict causal cone and (ii) all Quantum Cellular Automata (QCA) can be represented as MPUs. then introduce natural generalization latter, obtained by allowing an additional operator acting on their aux...
