Reversible Logic is gaining significant consideration as the potential logic design style for implementation in modern nanotechnology and quantum computing with minimal impact on physical entropy .Fault Tolerant reversible logic is one class of reversible logic that maintain the parity of the input and the outputs. Significant contributions have been made in the literature towards the design of...

We present a general method to construct fault-tolerant quantum logic gates with a simple primitive, which is an analog of quantum teleportation. The technique extends previous results based on traditional quantum teleportation @Gottesman and Chuang, Nature ~London! 402, 390 ~1999!# and leads to straightforward and systematic construction of many fault-tolerant encoded operations, including the...

A Fault tolerant reversible logic has gained importance as they consume low power and less heat dissipation. The benefits of logical reversibility can be gained only after employing physical reversibility. Every future technology will have to use reversible gates in order to reduce power. This paper proposed a new fault tolerant reversible 4*4 RR-gate which satisfies the reversible and parity p...

The implementation of fault-tolerant quantum gates on encoded logic qubits is considered. It is shown that transversal implementation of logic gates based on simple geometric control ideas is problematic for realistic physical systems suffering from imperfections such as qubit inhomogeneity or uncontrollable interactions between qubits. However, this problem can be overcome by formulating the t...

Threshold Logic gate is used as design abstraction for most nano devices and perceived as an alternate emerging technology to CMOS implementation. It is vulnerable to manufacturing inaccuracies that alter weight values which inadvertently affect the functionality of the gate. Hence fault tolerance should be taken in to consideration during the design of threshold logic gates to tolerate manufac...

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...

This paper proposes a novel reversible logic gate, NFT. It is a parity preserving reversible logic gate, that is, the parity of the outputs matches that of the inputs. We demonstrate that the NFT gate can implement all Boolean functions. It renders a wide class of circuit faults readily detectable at the circuit’s outputs. The proposed parity preserving reversible gate, allows any fault that af...
