Quantum Heterodyne Sensing of Nuclear Spins via Double Resonance
Jonas Meinel, Minsik Kwon, Durga Dasari +5
Nanoscale nuclear magnetic resonance (NMR) signals can be measured through hyperfine interaction to paramagnetic electron sensor spins. A heterodyne approach is widely used to over…
Integrated and portable magnetometer based on nitrogen-vacancy ensembles in diamond
Felix M. Stürner, Andreas Brenneis, Thomas Buck +13
Magnetic field sensors that exploit quantum effects have shown that they can outperform classical sensors in terms of sensitivity enabling a range of novel applications in future,…
Diamond magnetometry and gradiometry towards subpicotesla DC field measurement
Chen Zhang, Farida Shagieva, Matthias Widmann +11
Nitrogen vacancy (NV) centers in diamond have developed into a powerful solid-state platform for compact quantum sensors. However, high sensitivity measurements usually come with a…
Quantum Metrology with Strongly Interacting Spin Systems
Hengyun Zhou, Joonhee Choi, Soonwon Choi +10
Quantum metrology makes use of coherent superpositions to detect weak signals. While in principle the sensitivity can be improved by increasing the density of sensing particles, in…
Experimental and theoretical analysis of noise strength and environmental correlation time for ensembles of nitrogen-vacancy centers in diamond
Kan Hayashi, Yuichiro Matsuzaki, Takaki Ashida +8
We experimentally and theoretically investigate the Hahn echo decay curve for nitrogen vacancy centers in diamond with different spin concentrations. The Hahn echo results show a n…
Probing quantum thermalization of a disordered dipolar spin ensemble with discrete time-crystalline order
Joonhee Choi, Hengyun Zhou, Soonwon Choi +8
We investigate thermalization dynamics of a driven dipolar many-body quantum system through the stability of discrete time crystalline order. Using periodic driving of electronic s…
