As energy efficiency becomes a paramount issue in this day and age, reversible computing may serve as a critical step towards energy conservation in information technology. The inputs of reversible computing elements define the outputs and vice versa. Some reversible gates such as the Fredkin gate are also universal; that is, they may be used to produce any logic operation. It is possible to fi...

The development of conventional computing technologies faces many challenges for the last couple of decades. Power dissipation in today's computer chips becomes dominant. Reversible computing is a promising alternative to these technologies, with applications in ultra-low power, nano computing, quantum computing, low power CMOS design, optical information processing, bioinformatics etc. In...

It is well-known that the Toffoli gate and the negation gate together yield a universal gate set, in the sense that every permutation of {0, 1}n can be implemented as a composition of these gates. Since every bit operation that does not use all of the bits performs an even permutation, we need to use at least one auxiliary bit to perform every permutation, and it is known that one bit is indeed...

Reversible logic gates are very much in demand for the future computing technologies as they are known to produce zero power dissipation under ideal conditions. This paper proposes an improved design of a multiplier using reversible logic gates. Multipliers are very essential for the construction of various computational units of a quantum computer. The quantum cost of a reversible logic circui...

In this paper, we show realization of macrolevel ternary reversible 2-qudit Feynman gate, 3-qudit controlled Feynman gate, and 3-qudit Toffoli gates using ternary reversible 1-qudit gates and 2-qudit Muthukrishnan-Stroud gates, which are theoretically realizable using quantum technology such as liquid ion trap [10]. Then we show the design of ternary reversible multiplexer and demultiplexer usi...

A clear protocol for synthesis of sequential reversible circuits from any particular gate library has been provided. Using that protocol, reversible circuits for SR latch, D latch, JK latch and T latch are designed from NCT gate library. All the circuits have been optimized with the help of existing local optimization algorithms (e.g. template matching, moving rule and deletion rule). It has be...

Considering the benefits of Quantum and Optics, if the logic gates in the quantum field and electronic structure are implemented using optical elements, then it will be benefited from advantages of Quantum and design, and these processing circuits can be used in optical computing and quantum computing, genetic processes, and other useful nanotechnology applications. In this study, we have intro...

The Fredkin gate (Fredkin & Toffoli, 1982) is a Boolean logic gate that consists of 3 inputs and 3 outputs. This gate is universal for computational logic, and more importantly, it is reversible in the sense that the mapping between its inputs and outputs is bijective. In this paper, we realize the logic function of a Fredkin gate based upon two simple reversible elements (Lee, et al. 2008) tha...

Reversible logic is becoming an important research area which aims mainly to reduce power dissipation during computing. In this paper we introduce a new parity preserving reversible gate PPPG (a 5x5 gate). This gate is universal in the sense it can synthesize any arbitrary Boolean function. It is also a parity preserving gate in which the parity of input matches the parity of the output. This p...
