Design of all optical reversible logic gates

Considering the benefits of Quantum and Optics, if the logic gates in the quantum field and electronic structure are implemented using optical elements, then it will be benefited from advantages of Quantum and design, and these processing circuits can be used in optical computing and quantum computing, genetic processes, and other useful nanotechnology applications. Advantages of reversible logic systems and circuits have drawn a significant interest in recent years as a promising computing paradigm having application in low power CMOS, quantum computing, nanotechnology, and optical computing. In this study, we have introduced reversible optical Double Feynman gate using optical Mach-Zehnder interferometer (MZI) switches with new design. The proposed optical Double Feynman gate will be optical logic gate and reversible. As the proposed gate is a complete one, it can implement all the MZI-based quantum circuits.
