This article is an attempt to generalize the classical theory of reversible computing, principally developed by Bennet [IBM J. Res. Develop., 17(1973)] and by Fredkin and Toffoli [Internat. J. Theoret. Phys., 21(1982)], to the quantum case. This is a fundamental step towards the construction of a quantum computer because a time efficient quantum computation is a reversible physical process. The...

We introduce a new model of cellular automaton called a one-dimensional number-conserving partitioned cellular automaton (NC-PCA). An NC-PCA is a system such that a state of a cell is represented by a triple of non-negative integers, and the total (i.e., sum) of integers over the connguration is conserved throughout its evolving (computing) process. It can be thought as a kind of modelization o...

The greater part of the reversible data hiding approaches proposed so far fuse a lossless information compression stage. The utilization of an elaborate data compression stage increases the complexity of watermarking. There are some watermarking plans that don't depend on extra data compression, with respect to example, circular histogram interpretation schemes. In this paper a survey is presen...

Page | 60 Capacity Enhancement of Reversible Data Hiding Technique Using Adaptive Embedding Cheenu Bansal, Preeti Gupta ABSTRACT: Reversible data hiding is current research area in field of data hiding. Reversible data hiding is defined as the process of hiding secret data in such a way that at receiver side both secret message and cover image can be recovered. This kind of reversibility is req...

| An 8 x 8-b nRERL serial multiplier is implemented in a 0.6m n-well 3-metal CMOS process. nRERL (nMOS Reversible Energy Recovery Logic) is a new reversible adiabatic logic circuit, which can be operated at the leakage-current level for ultralow-energy applications. Measurement results showed that the nRERL serial multiplier consumed only 0.9 % of the energy dissipation of the static CMOS one a...

We present a new protocol for realizing reversible distributed programs with CSP style communication. While this work was motivated by the desire to implement reversible process algebras, the protocol may have other interesting uses in distributed systems including checkpointing, speculative real-time simulation, and transaction synchronization. The protocol may be efficiently implemented in ha...

The law of entropy increase for bodies in mutual thermal contact may be argued using the fact that final temperature process is higher than a reversible work extraction.

Reversible logic is experience renewed interest as we are approach the limits of CMOS technologies. While physical implementations of reversible gates have yet to materialize, it is safe to assume that they will rely on faulty individual components. In this work we present a present a method to provide fault tolerance to a reversible circuit based on invariant relationships.

Existing systems that support semistructured views do not maintain semantics during the process of designing views. Thus, there is no guarantee that the views obtained are valid and reversible views. In this paper, we propose an approach to designing valid and reversible semistructured views. We employ four types of view operators, namely, select, drop, join and swap operators, and develop a se...

The reduction process for some quinones has been studid by cyclic voltammeby, rotating disk electrode voltammetry and chronopotentiometry in chloroform at platinum, gold and glassy carbon electrodes using tetrabutylmonium perchlorate (TB AP) as supporting eiectrolyte. The results obtained from this study reveal that the reduction of the quinones is two one-electron processes, the first redu...
