Quantum walks via quantum cellular automata [PDF]

open access: yesQuantum 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 amount of resources (in terms of effective Hilbert space dimension), various models of quantum walks.

PLAs in Quantum-Dot Cellular Automata

IEEE Transactions on Nanotechnology, 2006
Various implementations of the quantum-dot cellular automata (QCA) device architecture may help many performance scaling trends continue as we approach the nanoscale. Experimental success has led to the evolution of a research track that looks at QCA-based design.

Quantum cellular automata

Nanotechnology, 1993
The authors formulate a new paradigm for computing with cellular automata (CAS) composed of arrays of quantum devices-quantum cellular automata. Computing in such a paradigm is edge driven. Input, output, and power are delivered at the edge of the CA array only; no direct flow of information or energy to internal cells is required.

Periodicity in Quantum Cellular Automata

2012
Studies of quantum computer implementations suggest cellular quantum computer architectures. These architectures are based on the evolution of quantum cellular automata, which can possibly simulate both quantum and classical physical systems and processes.

Dilatability to Quantum Linear Cellular Automata

2010 12th International Symposium on Symbolic and Numeric Algorithms for Scientific Computing, 2010
Reversibility is one of the most important characteristics of microscopic mechanisms in physics. It is our aim in this paper to describe some classes of linear cellular automata(LCAs) that can be studied in terms of an associated reversibleLCA. We prove that any given LCA having as local transition map a row contraction can be dilated to a LCA having a

Nonlocal computation in quantum cellular automata

Physical Review A, 1993
Quantum cellular automata (QCA) have been introduced [G. Gr\"ossing and A. Zeilinger, Complex Syst. 2, 197 (1988); 2, 611 (1988)] as n-dimensional arrays of discrete sites characterized by a complex number whose absolute square lies between 0 and 1 such that each site represents a quantum-mechanical probability amplitude.
