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…
