Predictive model accurately estimates NV position and frequency

Abstract

We report an experimental design where the position and resonance frequency of the Nitrogen Vacancy (NV) in a diamond are correlated with the room temperature. A simple model trained on the interpolated correlation data predicts both quantities. The predictive tracking of the NV's location enables continuous operation of the NV quantum computer under ambient conditions for a week without recalibration.
