Reversible logic circuits have emerged as a promising technology having its applications in low power CMOS, Quantum Computing, nanotechnology, and optical computing. Power is the major constraint for any circuit Each circuit demands not only low power, but fast speed. This paper is focused on the efficient design of the full Adder/Subtractor with the help of half adder subtractor with single co...

This paper presents an important result addressing a fundamental question in synthesizing binary reversible logic circuits for quantum computation. We show that any even-reversible-circuit of n (n > 3) qubits can be realized using NOT gate and Toffoli gate (‘2’-ControlledNot gate), where the numbers of Toffoli and NOT gates required in the realization are bounded by (n+ n3 )(3×2 2n−3−2n+2) and ...

This paper investigates a universal approach of synthesizing arbitrary ternary logic circuits in quantum computation based on the truth table technology. It takes into account of the relationship of classical logic and quantum logic circuits. By adding inputs with constant value and garbage outputs, the classical non-reversible logic can be transformed into reversible logic. Combined with group...

Reversible logic design attracts more interest due to its low power consumption. A lot of research has been done in combinational as well as sequential design of reversible circuits. As far as it is known, this is the first attempt to apply reversible logic to synchronous counters design using T flipflop. In this paper we have also proposed a new reversible gate which can be used as copying gat...

Reversible logic gates were previously implemented in superconducting circuits as adiabatic-reversible gates, which are powered with a sufficiently slow clock. In contrast, we studying ballistic-reversible where fluxons serve to both encode the information and power gates. No is applied gate apart from energy of input fluxons, two possible flux polarities represent bit states. Undamped long Jos...

In recent past, reversible logic is emerged as a promising computing paradigm with applications in low-power CMOS, quantum computing, optical computing and nanotechnology. Optical logic gates become potential component to work at macroscopic (light pulses carry information), or quantum (single photon carries information) levels with high efficiency. In this paper, we propose a novel scheme of T...

Power dissipation is one of the important factor in digital circuit design. Landauer's principle states that logic computations which are not reversible necessarily generate KT*ln2 Joules of heat energy for every bit of information that is lost, where k is Boltzmann's constant and T the absolute temperature at which computation is performed. Reversibility is the property of digital circuits in ...
