The action of the c-NOT logic gate is to swap two of the spin populations. Logic gates such as these, which can be expressed as a truth table and which are unitary, are necessarily permu-
A NOR gate is a logic gate which gives a positive output only when both inputs are negative. Like NAND gates, NOR gates are so-called “universal gates” that can be combined to form any other kind of logic gate.
The implementation of all optical NAND logic gate is one of the most important aspects. The universal logic gate is one of the most essential logic gates. Hence, it is interesting to implement the NAND logic functionality in the optical domain using the micro-ring resonator structure. However, the symbol and truth table of NAND logic gate can be represented by the Fig.
Steps to be followed in the process of implementation of Logic Gates: Step 1: For NAND implementation, add Bubbles at the outputs of AND gates and at the inputs of OR gates.

Boolean logic in the form of simple gates is very straightforward. From simple gates you can create more complicated functions, like addition. Physically implementing the gates is possible and easy. From those three facts you have the heart of the digital revolution, and you understand, at the core, how computers work.

A reversible gate has the equal number of inputs and outputs and one-to-one mappings between input vectors and output vector, thus the vector of input states can be always reconstructed from the vector of output states. A gate with k inputs and k outputs is called a k*k gate. Reversible logic Gate has one of the most important approaches for the power factor with its application in low power
