Description
Summary:The most important component of implementation of quantum systems is the quantum gate. Efficient implementation of quantum gates is an important challenge for the development of quantum computing. This research is one of the first approaches in the field of implementation of quantum gates by logic gates using crystal photonics. In this paper, a new structure of CNOT quantum gate is designed using two-dimensional photonic crystals and implemented using XOR logic gate. The overall size of this proposed structure based on photonic crystal with silicon rods is equal to 25 × 35 μm, and the response time is equal to 0.53 ps. The proposed structure offers small area and fast response time that makes it suitable for high-speed applications. Separation between input and output ports is one of the features that has been given special attention in the design.
