- Abstract: Versatile nanoscale sensors that are susceptible to changes in a variety of
physical quantities often exhibit limited selectivity. This paper reports a
novel scheme based on microwave-dressed spin states for optically probed
nanoscale temperature detection using diamond quantum sensors, which provides
selective sensitivity to temperature changes. By combining this scheme with a
continuous pump-probe scheme using ensemble nitrogen-vacancy centers in
nanodiamonds, a sub-microsecond temporal resolution with thermal sensitivity of
3.7 K$\cdot$Hz$^{-1/2}$ that is insensitive to variations in external magnetic
fields on the order of 2 G is demonstrated. The presented results are favorable
for the practical application of time-resolved nanoscale quantum sensing, where
temperature imaging is required under fluctuating magnetic fields.
