Designs of BCD Adder Based on Excess-3 Code in Quantum-Dot Cellular Automata
IEEE Transactions on Circuits and Systems - II - Express Briefs, 2023Quantum-dot cellular automata (QCA) is a novel nano-electronic technology. QCA has attracted wide attention due to its extremely small feature sizes at the molecular or even atomic scale and ultra-low power consumption, making it a promising candidate to

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
2012Studies 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, 2010Reversibility 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

Molecular Quantum-Dot Cellular Automata
Journal of the American Chemical Society, 2003Molecular electronics is commonly conceived as reproducing diode or transistor action at the molecular level. The quantum-dot cellular automata (QCA) approach offers an attractive alternative in which binary information is encoded in the configuration of charge among redox-active molecular sites.

Complex Syst., 1988
Cellular automata research was extended into the region of quantum mechanics, which extension was necessitated by smaller size of automaton machines so that quantum effects cannot be neglected. The uncertainty whether the value at a given site is 0 or 1 at a given instant of time is expressed by introducing probability amplitudes.

Nonlocal computation in quantum cellular automata
Physical Review A, 1993Quantum 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.

Quantum Walks and Quantum Cellular Automata
2008The quantum walk is a generalization of classical random walks. Considerable work has been recently investigated on quantum walks in connection with quantum computing. The walk can be considered as a class of quantum cellular automata. There exists a one-to-one correspondence between them in a more general setting. Moreover we consider another class of

Quantum-Dot cellular automata divider
2017 6th Mediterranean Conference on Embedded Computing (MECO), 2017One of the most important mathematical operations is division. An efficient divider can be of great assistance in designing arithmetic circuits. The Quantum cellular automata (QCA) is an encouraging technology which seems to be a good successor of existing digital systems.
