Reversible logic is one of the flourishing importance to many futuristic technologies. A reversible circuit maps each input vector into a unique output vector. There should not be any information loss in the circuit, because it is proved that each irreversible bit operation dissipate kTln2 amount of energy, but there are so many fields such as cryptography, optical computing, DNA computing etc....

Multiplier circuits play an important role in reversible computation, which is helpful in diverse areas such as low power CMOS design, optical computing, DNA computing and bioinformatics. Here we propose a new reversible multiplier circuit with optimized hardware complexity. The optimized multiplier circuit is compared with the earlier proposals. We have shown that the quantum cost of earlier p...

A logically reversible Feynman gate was successfully realized under enzyme-free conditions by integrating graphene oxide and DNA for the first time. The gate has a one-to-one mapping function to identify inputs from the corresponding outputs. This type of reversible logic gate may have great potential applications in information processing and biosensing systems.

At present, Boolean algebra based computations by the use of silicon based semiconductor technology are irreversible in nature. This is due to the mismatch of number of inputs and outputs. Reversible logic circuit maps unique input to the output and ensure one to one mapping and basis for emerging applications like low-power design, quantum computation, optical computing, bioinformatics and nan...

The Fredkin three-bit gate is universal for computational logic, and is reversible. Classically, it is impossible to do universal computation using reversible two-bit gates only. Here we construct the Fredkin gate using a combination of six two-body reversible (quantum) operators.

Testing of Sequential circuits can be done by two test vectors (all 1’s and all 0’s) if the circuits were based on the conservative logic. The circuit is made to be tested by designing the circuit with the help of Reversible logic gates. Toffoli gate is used as reversible gate in this paper. Sequential circuits such as latches, flip flops are designed with the help of conservative logic reversi...

We present a complete classification of all possible sets of classical reversible gates acting on bits, in terms of which reversible transformations they generate, assuming swaps and ancilla bits are available for free. Our classification can be seen as the reversible-computing analogue of Post’s lattice, a central result in mathematical logic from the 1940s. It is a step toward the ambitious g...

This paper proposes two reversible logic gates, HNFG and HNG. The first gate HNFG can be used as two Feynman Gates. It is suitable for a single copy of two bits with no garbage outputs. It can be used as “Copying Circuit” to increase fan-out because fan-out is not allowed in reversible circuits. The second gate HNG can implement all Boolean functions. It also can be used to design optimized add...

Nowadays, reversible logic is one of the most important issue which has emerged as a promising technology having its applications in low power CMOS, quantum computing, nanotechnology and optical computing. Reversible logic circuits give less power dissipation as well as distinct output that is assigned for each distinct input. The classical set of gates such as the NAND, AND, NOR, OR, XOR and X...

Power consumption is one of the important issues in VLSI design. Reversible logic produces zero power; therefore, nowadays researchers attend to it in order to optimize power. In the digital systems, one of the methods of achieving to fault tolerance is parity preserving. This paper proposes a new parity preserving reversible gate, PPRG. The most significant aspect of the PPRG gate is that it c...
