This study introduces maximum likelihood estimation (MLE) into temperature sensing using nitrogen-vacancy (NV) centers in nanodiamonds and evaluates the extent to which the speed and precision of temperature estimation can be improved.
By systematically comparing the proposed MLE-based analysis with conventional fitting-based methods, we quantitatively assess the performance gains achievable under identical measurement conditions.
The results clarify the advantages of MLE for high-speed and high-precision NV-center thermometry, particularly in regimes relevant to time-resolved temperature measurements.
