Excited-state spectroscopy of spin defects in hexagonal boron nitride
Pei Yu, Haoyu Sun, Mengqi Wang +8
We used optically detected magnetic resonance (ODMR) technique to directly probe electron-spin resonance transitions in the excited state of negatively-charged boron vacancy (VB-)…
Identity Test of Single NV Centers in Diamond at Hz-Precision Level
Tianyu Xie, Zhiyuan Zhao, Maosen Guo +3
Atomic-like defects in solids are not considered to be identical owing to the imperfections of host lattice. Here, we found that even under ambient conditions, negatively charged n…
Resonant Quantum Principal Component Analysis
Zhaokai Li, Zihua Chai, Yuhang Guo +6
Principal component analysis has been widely adopted to reduce the dimension of data while preserving the information. The quantum version of PCA (qPCA) can be used to analyze an u…
Beating the Standard Quantum Limit under Ambient Conditions with Solid-State Spins
Tianyu Xie, Zhiyuan Zhao, Xi Kong +10
Precision measurement plays a crucial role in all fields of science. The use of entangled sensors in quantum metrology improves the precision limit from the standard quantum limit…
