Reversible circuits find applications in many areas of Computer Science including Quantum Computation. This paper examines the testability of an important subclass of reversible logic circuits that are composed of k-wire controlled NOT (kCNOT with k -CNOT gate can be implemented using an irreversible k-input AND gate and an EXOR gate. A reversible k-CNOT circuit where each k-CNOT gate is realiz...

This paper provides the initial threshold to building of more complex system having reversible sequential circuits as a primitive component and which can execute more complicated operations using quantum computers. The reversible circuits form the basic building block of quantum computers as all quantum operations are reversible. The important reversible gates used for reversible logic synthesi...

Reversible Logic is an emerging technology; it has hellocious applications in various fields. Reversible logic implementation reduces loss of entropy because of bit manipulations. Conservative reversible logic gate obeys reversible logic rules and also satisfies the property that there is equal number of 1s in the outputs as in the inputs. In this work, modified design of SCRL (Super Conservati...

Testable fault tolerant system design has become vital for many safety critical applications. On the other hand, reversible logic is gaining interest in the recent past due to its less heat dissipating characteristics. Any Boolean logic function can be implemented using reversible gates. This paper proposes a technique to convert any reversible logic gate to a testable gate that is also reversi...

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. In this paper we propose a new reversible gate usin...

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 $A(\mathbb Z_2^n)$...

Reversible logic is one of the emerging technologies having promising applications in quantum computing. This project will deal with the design of a 16 bit reversible Arithmetic Logic Unit (ALU) with 15 operations is presented by making use of Double Peres gate, Fredkin gate, Toffolli gate, DKG gate and NOT gate. A new VLSI architecture for ALU using reversible logic gates is proposed. ALU is o...

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...
