C-ELEMENT DESIGN IN QUANTUM DOT CELLULAR AUTOMATA
Jordanian Journal of Computers and Information Technology, 2021 The continuous market demands for high-performance and energy-efficient computing systems have steered the computational paradigm and technologies towards nano-scale quantum dot cellular automata (QCA).

Quantum Cellular Automata, Tensor Networks, and Area Laws. [PDF]
Physical Review Letters, 2020 Quantum cellular automata are unitary maps that preserve locality and respect causality. We identify them, in any dimension, with simple tensor networks (projected entangled pair unitary) whose bond dimension does not grow with the system size.

Ergodicity of quantum cellular automata [PDF]
Journal of Statistical Physics, 1996 We define a class of dynamical maps on the quasi-local algebra of a quantum spin system, which are quantum analogues of probabilistic cellular automata. We develop criteria for such a system to be ergodic, i.e., to possess a unique invariant state. Intuitively, ergodicity obtains if the local transition operators exhibit sufficiently large disorder ...

RETRACTED ARTICLE: A new design for 4-bit RCA using quantum cellular automata technology
Optical and quantum electronics, 2021 Since the scaling of transistors is growing rapidly, the need for an efficient alternative for the Complementary Metal-Oxide-Semiconductor (CMOS) technology to obtain further and extra processes in the circuits has been known as the main problem.

Fermionic quantum cellular automata and generalized matrix-product unitaries [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2020 In this paper, we study matrix-product unitary operators (MPUs) for fermionic one-dimensional chains. In stark contrast to the case of 1D qudit systems, we show that (i) fermionic MPUs (fMPUs) do not necessarily feature a strict causal cone and (ii) not ...

A quantum Samaritan’s dilemma cellular automaton [PDF]
Royal Society Open Science, 2017 The dynamics of a spatial quantum formulation of the iterated Samaritan’s dilemma game with variable entangling is studied in this work. The game is played in the cellular automata manner, i.e. with local and synchronous interaction. The game is assessed

Probabilistic cellular automata for interacting fermionic quantum field theories
Nuclear Physics B, 2021 A classical local cellular automaton can describe an interacting quantum field theory for fermions. We construct a simple classical automaton for a particular version of the Thirring model with imaginary coupling. This interacting fermionic quantum field
