We explore applications of silicon carbide photonics in quantum simulation. We design a low-loss triangular photonic crystal molecule with embedded color centers, and explore the formation of hybridized light-matter states in this system.

As a cutting-edge quantum information research system at the intersection of "quantum information" and "integrated circuits", silicon carbide color center has become one of the important solid-state quantum systems in recent years. Silicon carbide color center system has the following characteristics :1) Silicon carbide is a mature semiconductor material, quantum information technology based on silicon carbide color center is easy to integrate with semiconductor industry technology; 2) Silicon carbide color center fluorescence in the near infrared band, which is conducive to transmission in optical fiber communication network; 3) Silicon carbide color center spin coherence time is long, easy to perform more quantum algorithms. This report mainly introduces the research progress of quantum control and quantum precision measurement of silicon carbide color centers, including the basic knowledge of silicon carbide color centers, the preparation, observation and quantum control of its spin quantum states, as well as the application of this system in the fields of quantum control and quantum precision measurement.
