Active Optical Frequency Measurements with Superradiance Prolonged by a Modulated Magnetic Field
Huihui Yu, Shi-Lei Su, Chongxin Shan +2
Superradiant emission from long-lived excited states of an atomic ensemble confined in an optical cavity constitutes a practical source of light with narrow linewidth. In the pulse…
Real-Time Magnetic Field Sensing based on Microwave Frequency Modulated Photocurrent of Nitrogen-Vacancy Centers in Diamond
Xuan-Ming Shen, Qilong Wu, Huihui Yu +6
While photoelectric detection of magnetic resonance (PDMR) can be applied to miniaturize nitrogen-vacancy (NV) center-based quantum sensors, real demonstration of PDMR-based magnet…
Stochastic Mean-field Theory for Conditional Spin Squeezing by Homodyne Probing of Atom-Cavity Photon Dressed States
ZhiQing Zhang, HaiZhong Guo, Lingrui Wang +4
Projective measurements of collective observables can be employed to herald the preparation of entangled states of quantum systems, and the resulting conditional dynamics is usuall…
Fiber-integrated NV Magnetometer with Microcontroller-based Software Lock-in Technique
Qilong Wu, Xuan-Ming Shen, Yuan Zhang +9
Fiber-integrated nitrogen-vacancy (NV) magnetometers possess high sensitivity, integration, and flexibility, and thus have been explored extensively for industrial applications. Wh…
Long-exposure Camera Readout for Coherent Control of Nitrogen-Vacancy Center Spins in Diamond
Jiahui Chen, Qilong Wu, Huihui Yu +4
Camera-based wide-field quantum noise spectroscopy (QNS) with nitrogen-vacancy (NV) center spins in diamond can be used to extract DC and AC magnetic field noise with sub-micromete…
Superradiant Echoes Induced by Multiple Re-phasing of NV Spin Sub-ensembles Grating at Room Temperature
Qilong Wu, Yuan Zhang, Huihui Yu +2
In this Letter, we propose that superradiant echoes can be achieved at room temperature by applying a laser illumination and a microwave Hahn echo sequence to a diamond with a high…
