Implementation of quantum optical tristate CNOT gate using frequency encoding principle with a semiconductor optical amplifier

Abstract

Controlled NOT (CNOT) gate is well known because of its several advantages in quantum computing and information processing. In the area of quantum computing, several methods of CNOT gates were established in last few years. In this paper, we propose a new approach of implementation of tristate CNOT operation with light as information carrying signal. To do this, the frequency encoding method has been exploited for successful realization of the CNOT gate with light.
