An Energy-Aware Model for the Logic Synthesis of Quantum-Dot Cellular Automata

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2018
Quantum-dot cellular automata (QCA) are an emerging field-coupled nanotechnology with remarkable performance and energy efficiency. In order to enable the exploration of this technology, we propose a model for the logic synthesis of QCA circuits that ...

Cellular Automata

Journal of Organizational and End User Computing, 2017
Cellular automata (CA) are discrete dynamical systems consist of a regular finite grid of cell; each cell encapsulating an equal portion of the state, and arranged spatially in a regular fashion to form an n-dimensional lattice. A cellular automata is like computers, data represented by initial configurations which is processed by time evolution to ...

Elementary Cellular Automata with Memory

Complex Systems
Standard cellular automata (CA) are ahistoric (memoryless), that is, the new state of a cell depends on the neighborhood configuration of only the preceding time step.

Classification of Quantum Cellular Automata

Communications in Mathematical Physics, 2019
There exists an index theory to classify strictly local quantum cellular automata in one dimension (Fidkowski et al. in Interacting invariants for Floquet phases of fermions in two dimensions, 2017. arXiv:1703.07360 ; Gross et al. in Commun Math Phys 310(

Cellular automata synchronization

Information Sciences, 1976
The first part of this paper deals with the Firing Squad Synchronization problem extended to networks however connected. A new class of configurations called "flower graphs" is presented whose synchronization is useful to reduce synchronization time for any graph. The second part investigates the lower bounds for synchronization time from a theoretical

Statistical mechanics of cellular automata

, 1983
Cellular automata are used as simple mathematical models to investigate self-organization in statistical mechanics. A detailed analysis is given of ''elementary'' cellular automata consisting of a sequence of sites with values 0 or 1 on a line, with each

Nontrivial Quantum Cellular Automata in Higher Dimensions

Communications in Mathematical Physics, 2018
We construct a three-dimensional quantum cellular automaton (QCA), an automorphism of the local operator algebra on a lattice of qubits, which disentangles the ground state of the Walker–Wang three-fermion model.

Integrable cellular automata

Physics Letters A, 1992
Abstract We present a general procedure to associate hierarchies of cellular automata with given spectral problems choosing, as illustrative example, the discrete Schrodinger problem. For these cellular automata we construct a countable number of constants of motion using standard spectral techniques and we perform numerical experiments showing ...
