Density Classification with Non-Unitary Quantum Cellular Automata [PDF]

Entropy
The density classification (DC) task, a computation which maps global density information to local density, is studied using one-dimensional non-unitary quantum cellular automata (QCAs).

Generative Music with Partitioned Quantum Cellular Automata

Applied Sciences, 2023
Cellular automata (CA) are abstract computational models of dynamic systems that change some features with space and time. Music is the art of organising sounds in space and time, and it can be modelled as a dynamic system.

A Gentle Introduction to Lattice Field Theory [PDF]

Entropy
The principles of Lattice Field Theory (LFT), in particular Lattice Gauge Theory (LGT), are explained for a nonspecialist audience. We describe some of the successes of the program; we also discuss the relationship between LFT and Quantum Cellular ...

A compact and power efficient full adder-subtractor layout in QCA technology. [PDF]

PLoS ONE
The pursuit of miniaturizing digital circuits and reducing power consumption has focused attention on non-traditional computing technologies. Among these technologies, quantum dot cellular automata (QCA) stand out as a promising alternative to ...

Effectiveness of Molecules for Quantum Cellular Automata as Computing Devices

Journal of Low Power Electronics and Applications, 2018
Notwithstanding the increasing interest in Molecular Quantum-Dot Cellular Automata (MQCA) as emerging devices for computation, a characterization of their behavior from an electronic standpoint is not well-stated.

A review of Quantum Cellular Automata [PDF]

Quantum, 2020
Discretizing spacetime is often a natural step towards modelling physical systems. For quantum systems, if we also demand a strict bound on the speed of information propagation, we get quantum cellular automata (QCAs).

Functorial Evolution of Quantum Fields

Frontiers in Physics, 2021
We present a compositional algebraic framework to describe the evolution of quantum fields in discretised spacetimes. We show how familiar notions from Relativity and quantum causality can be recovered in a purely order-theoretic way from the causal ...

A Novel Enhanced-Majority-Voter Universal Gate in Quantum Dot Cellular Automata with Energy Dissipation Analysis [PDF]

Журнал нано- та електронної фізики, 2017
The Quantum effects instigate to dominate device recital when transistor geometries are abridged. Sometimes, transistors refrain to have the properties that mark them beneficial for computational designs.

Computational universality of symmetry-protected topologically ordered cluster phases on 2D Archimedean lattices [PDF]

Quantum, 2020
What kinds of symmetry-protected topologically ordered (SPTO) ground states can be used for universal measurement-based quantum computation in a similar fashion to the 2D cluster state?

Directed percolation in nonunitary quantum cellular automata

Physical Review Research, 2021
Probabilistic cellular automata (CA) provide a classic framework for studying nonequilibrium statistical physics on lattices. A notable example is the Domany-Kinzel CA, which has been used to investigate the process of directed percolation and the ...
