Subsystem symmetries, quantum cellular automata, and computational phases of quantum matter [PDF]
Quantum, 2019 Quantum phases of matter are resources for notions of quantum computation. In this work, we establish a new link between concepts of quantum information theory and condensed matter physics by presenting a unified understanding of symmetry-protected ...

Quantum walks via quantum cellular automata [PDF]
Quantum Information Processing, 2018 Very much as its classical counterpart, quantum cellular automata are expected to be a great tool for simulating complex quantum systems. Here we introduce a partitioned model of quantum cellular automata and show how it can simulate, with the same ...

Clifford Quantum Cellular Automata from Topological Quantum Field Theories and Invertible Subalgebras [PDF]
PRX QuantumWe present a general framework for constructing quantum cellular automata (QCAs) from topological quantum field theories (TQFTs) and invertible subalgebras (ISAs) using the cup-product formalism.

The Group Structure of Quantum Cellular Automata [PDF]
Communications in Mathematical Physics, 2019 We consider the group structure of quantum cellular automata (QCA) modulo circuits and show that it is abelian even without assuming the presence of ancillas, at least for most reasonable choices of control space; this is a corollary of a general method ...

Reversible Quantum-Dot Cellular Automata-Based Arithmetic Logic Unit
Nanomaterials, 2023 Quantum-dot cellular automata (QCA) are a promising nanoscale computing technology that exploits the quantum mechanical tunneling of electrons between quantum dots in a cell and electrostatic interaction between dots in neighboring cells. QCA can achieve

A Gentle Introduction to Lattice Field Theory [PDF]
EntropyThe 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 ONEThe 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.

DHR bimodules of quasi-local algebras and symmetric quantum cellular automata [PDF]
Quantum Topology, 2023 For a net of C*-algebras on a discrete metric space, we introduce a bimodule version of the DHR tensor category and show it is an invariant of quasi-local algebras under isomorphisms with bounded spread. For abstract spin systems on a lattice $L\subseteq

Quantum Cellular Automata for Quantum Error Correction and Density Classification. [PDF]
Physical Review Letters, 2023 Quantum cellular automata are alternative quantum-computing paradigms to quantum Turing machines and quantum circuits. Their working mechanisms are inherently automated, therefore measurement free, and they act in a translation invariant manner on all ...
