Abstract:

Quantum sensing, as a core branch of quantum information technology, utilizes quantum effects such as quantum superposition and quantum entanglement to break through the limits of classical physics and achieve ultra-high precision measurement of physical quantities. Compared to traditional quantum sensing materials, solid-state color center materials have core advantages such as being embedded in a rigid lattice, being able to stably maintain quantum coherence at room temperature in an atmosphere, being biocompatible and environmentally tolerant, and having a long coherence time for spin states. These characteristics provide high-quality material support for the industrialization of quantum sensing. This article first introduces the development trends of quantum precision measurement and sensing technology, and elaborates on the importance of quantum sensing. Then, it focuses on reviewing typical solid-state color center quantum sensing types such as diamond nitrogen-vacancy color centers, group-IV color centers, and hexagonal boron nitride color centers, systematically introducing their structures and applications. Finally, it briefly surveys other quantum sensing materials and discusses the development prospects and challenges of solid-state color center quantum sensing.
