A quantum-dot cellular automata(QCA) is important technology to be with CMOS. QCA is expected to reach very high operating frequencies and significant reduction of power consumption. Reversible logic is an one-to-one mapping between the input and output vectors. Reversible logic is significant in QCA circuit with almost zero power dissipation.

The paper discusses the asymptotic depth of a reversible circuit consisting of NOT, CNOT and 2-CNOT gates. Reversible circuit depth function $D(n, q)$ for a circuit implementing a transformation $f\colon \mathbb Z_2^n \to \mathbb Z_2^n$ is introduced as a function of $n$ and the number of additional inputs $q$. It is proved that for the case of implementing a permutation from $A(\mathbb Z_2^n)$...

In this paper we propose a new concept for multiplication by using modified booth algorithm and reversible logic functions. Modified booth algorithm produces less delay compare to normal multiplication process. Modified booth algorithm reduces the number partial products which will reduces maximum delay count a the output. by combining modified booth algorithm with reversible gate logic it will...

In a recent paper M. Lopez-Suarez, I. Neri, and L. Gammaitoni (LNG) present a concrete realization of the Boolean Or irreversible gate, but contrary to the standard Landauer principle, with an arbitrary small dissipation of energy. A Popperian good falsification! In this paper we discuss a theoretical description of the LNG gate which is indeed a 3in/3out self–reversible realization of the invo...

Reversible sequential circuits are going to be the significant memory blocks for the forthcoming computing devices for their ultra low power consumption. Therefore design of various types of latches has been considered a major objective for the researchers quite a long time. In this paper we proposed efficient design of reversible sequential circuits that are optimized in terms of quantum cost,...

Reversible logic has attracted much research interest over the last few decades, especially due to its application in quantum computing. In the construction of reversible gates from basic gates, ancilla bits are commonly used to remove restrictions on the type of gates that a certain set of basic gates generates. With unlimited ancilla bits, many gates (such as Toffoli and Fredkin) become unive...

Under ideal conditions, Reversible logic gates produce zero power dissipation. So these can be used for low power VLSI design. This paper proposes a new reversible parallel adder/subtractor using 4*4 Reversible DKG gate that can work singly as a reversible full adder and a full subtractor. A serial adder/subtractor is also designed in this paper using Reversible Universal Shift registers and DK...
