Dibit-based Frequency encoded Fredkin gate

Quantum gates are dependable in new fields, including superconducting flux 1 ogic, q uantum-dot c ellular automata, optical quantum computing, and quantum computing. Quantum gates such as the Feynman, double Feynman, Fredkin, Peres, and Toffoli have low power dissipation. For designing these gates in the electronic era, a bottleneck problem is the speed limitations of the electron and also the power dissipation due to the optoelectronic devices. Therefore realization of the quantum gates in all-optical (A-O) domain is an important issue. Therefore, a design of A-O Fredkin gate is proposed using optical-add/drop multiplexer (OADM) and reflective semiconductor optical amplifier (RSOA). I nt his d esign, we a lso i ntroduced t he dibit-based logic and frequency encoding scheme. The developed method is simulated using MATLAB.
