  Introduction • Quantum circuitsare collections of quantum gates interconnected by quantum wires. The actual structure of a quantum circuit, the number and the types of gates, as well as the interconnection scheme are dictated by the unitary transformation. • A physical implementation of a qubit could use the two energy levels of an atom. An excited state representing |1> and a ground state representing |0>. • A single qubit can be forced into a superposition of the two states denoted by the addition of the state vectors: |> =  |0> +  |1> • Where  and  are complex numbers and | | + |  | = 1

  Programming • Design ofreversible gates and various applications of it using Verilog HDL with Xilinx ISE version 13.1, spartan 3 FPGA. • Xilinx ISE is a software tool produced by Xilinx for synthesis and analysis of HDL designs. This tool enables the developer to synthesize their designs, perform time analysis, examine RTL diagrams, design reactions to different stimuli, and configure the target device with the programmer.

  Conclusion Though in ourdescription of quantum circuits we use the concepts input and output registers of qubits, we should be aware that physically, the input and the output of a quantum circuit are not separated as their classical counterparts are, this convention allows us to describe the effect of unitary transformation carried out by the circuit in a more coherent fashion.
