A Novel Design of Half Subtractor Using Reversible Feynman Gate in Quantum Dot Cellular Automata

Quantum dot Cellular Automata (QCA) is an emerging, promising alternative to CMOS technology that performs its task by encoding binary information on electronic charge configuration of a cell. All circuit based on QCA has an advantages of high speed, high parallel processing, high integrity and low power consumption. Reversible logic gates are the leading part in Quantum Dot cellular Automata. Reversible logic gates have an extensive feature that does not lose information. In this paper, the authors present a novel architecture of half sub-tractor gate design by reversible Feynman gate.
