The paper presents a reversible implementation of multiplexer and de-multiplexer, and evaluation of their quantum cost, gate count, garbage outputs and depth of the circuit. The simulation results are ...

The Half Adder is a basic digital circuit used for adding two 1-bit binary numbers. It has two inputs, 'a' and 'b', and two outputs, 'sum' and 'cout' (carry out). The Verilog code for the Half Adder ...
