An all-optical implementation of Fredkin gate using Kerr effect

Abstract:

Quantum gates are the important breakthrough in current computation and high-end data processing. Several quantum logic gates have been implemented in last few decades. In this paper, the idea of all-optical (photonic) Fredkin gate is proposed, which performs the swapping operation by a control signal. Corresponding simulation is also conducted with MATLAB, which shows the same result as the theoretical prediction.
