Rules for a cellular automaton to model quantum-dot cellular automata

Proceedings of the 2001 1st IEEE Conference on Nanotechnology. IEEE-NANO 2001 (Cat. No.01EX516), 2002
Quantum-dot cellular automata are one of several new device architectures whose operation is based on local interactions, much like cellular automata. We have implemented several rule sets for a cellular automaton that could be used to model the behavior of quantum-dot cellular automata and used them to test most of the wire and gate configurations ...

A New Nano-Scale and Energy-Optimized Reversible Digital Circuit Based on Quantum Technology

Electronics, 2022
A nano-scale quantum-dot cellular automaton (QCA) is one of the most promising replacements for CMOS technology. Despite the potential advantages of this technology, QCA circuits are frequently plagued by numerous forms of manufacturing faults (such as a

Ratchet Cellular Automata [PDF]

, 2002
In this work we propose a ratchet effect which provides a general means of performing clocked logic operations on discrete particles, such as single electrons or vortices. The states are propagated through the device by the use of an applied AC drive. We

Universal Reversible Combinational Circuit Design using Quantum Dot Cellular Automata

International Journal for Research in Applied Science and Engineering Technology, 2019
— Quantum-dot cellular automaton (QCA) is a novel step towards the VLSI design by replacing the traditional CMOS Technology. It might bypass the transistor paradigm to molecular –scale or nano scale computing.

Implementing controlled-NOT gate based on free spin qubits with semiconductor quantum-dot array [PDF]

, 2005
Based on electron spins in semiconductor quantum dots as qubits, a new quantum controlled-NOT (CNOT) gate is constructed in solid nanostructure without resorting to spin-spin interactions.

Local Unitary Quantum Cellular Automata [PDF]

, 2007
In this paper we present a quantization of Cellular Automata. Our formalism is based on a lattice of qudits, and an update rule consisting of local unitary operators that commute with their own lattice translations. One purpose of this model is to act as

Modeling tumor cell migration: from microscopic to macroscopic [PDF]

, 2009
It has been shown experimentally that contact interactions may influence the migration of cancer cells. Previous works have modelized this thanks to stochastic, discrete models (cellular automata) at the cell level.
