Quantum Geometry in Diamond Defects

<p>Recent years have witnessed rapid development in the field of quantum information science. Quantum technologies are promising to revolutionize many fields ranging from fast computation and simulation to precise sensing and secure communication. While the performance of quantum devices in the current noisy intermediate-scale quantum (NISQ) era is still limited exploring intriguing applications of various quantum systems has been an active research area. Among the many physical platforms solid-state spin defects such as nitrogen-vacancy (NV) center in diamond have attracted a lot of attentions thanks to their good controllability and long coherence time even at room temperature.</p>
