High-sensitivity magnetometry at room temperature with post-processed optical readout of single NV-centres

Not Accessible

Your library or personal account may give you access

Abstract

Optical readout from nanofabricated single NV centres is enhanced via Bayesian inference techniques, to demonstrate efficient magnetometry at room temperature conditions. We achieve experimentally Heisenberg-limited sensitivities O(100 nT s1/2), thus competing with state-of-art cryogenic set-ups.
