Quantum and reversible logic circuits have more advantages than the common circuits, like low power consumption. These circuits are good choice to design future computers. One of the important issues in reversible logic is parity preservation. If parity of inputs and outputs are equal in reversible gate, this gate will be parity preserve. Reversible circuits made by these gates are parity prese...

Overcoming the IC power challenge requires signal energy recovery, which can be achieved utilizing adiabatic charging principles and logically reversible computing in the circuit design. This paper demonstrates the energyefficiency of a Bennett-clocked adiabatic CMOS multiplier via a simulation model. The design is analyzed on the logic gate level to determine an estimate for the number of irre...

We present an overview and analysis of existing work in the design of online testable reversible logic circuits, as well as propose new approaches for the design of such circuits. We explain how previously proposed approaches are unnecessarily high in overhead and in many cases do not provide adequate fault coverage. Proofs of the correctness of our approaches are provided, and discussions of t...

A novel low power and Positive Feedback Adiabatic Logic (PFAL) 5-input OR Gate is presented in this paper. The power consumption and general characteristics of the PFAL 5 input OR gate are then compared against two low power 5-input OR Gate; Efficient Charge Recovery Logic (ECRL), Conventional CMOS 5-input OR Gate. The proposed PFAL 5-input OR Gate design was proven to be superior to the other ...

Reversible logic has two main properties. First, the number of inputs is equal to the number of outputs. Second, it implements a one-to-one mapping; i.e., one can reconstruct the inputs from the outputs. These properties enable its applications in building quantum computing architectures. In this paper we study reverse engineering of reversible logic circuits, including reverse engineering of n...

Reversible single-target gates are a generalization of Toffoli gates which are a helpful formal representation for the description of synthesis algorithms but are too general for an actual implementation based on some technology. There is an exponential lower bound on the number of Toffoli gates required to implement any reversible function, however, there is also a linear upper bound on the nu...

Reversible logic plays an important role in quantum computing. Several papers have been recently published on universality of sets of reversible gates. However, a fundamental unsolved problem remains: “what is the minimum set of gates that are universal for n-qubit circuits without ancillae bits”. We present a library of 2 gates which is sufficient to realize all reversible circuits of n variab...
