For example, an AND gate outputs 1 only if both inputs are 1, while an OR gate outputs 1 if either input is 1. There are seven basic types of logic gates: AND, OR, NOT, NAND, NOR, XOR and XNOR.

Reversible logic gate has gained importance in recent times due to its low power dissipation and less information loss. QCA on the other hand has low power consumption and has applications in ...
