基于室温单自旋磁共振技术的量子精密测量
摘要
The ability of penetrating deeply into single quantum system can help reveal the unique information of the quantum individuals used to be averaged by the ensemble statistics in traditional macroscopic measurement. The nitrogen-vacancy (NV) center in diamond, which has an ultralong coherence time and can be readout and manipulated through ODMR (optically detected magnetic resonance) techniques under room temperature, has been an important platform achieving quantum precision measurement and quantum information processing. Particularly in magnetometry, the researches on single spin imaging are in full swing. In this review we retrospect the work about quantum precision metrology based on the NV center, and introduce the progress in sensing magnetic field, electric field, mechanical system and temperature. We also discuss the possible developing directions in this area.
