Optimizing Data Processing for Nanodiamond Based Relaxometry

Adv Quantum Technol. (2023)

This article compares different methods for analyzing T1 data in nanodiamonds using nitrogen-vacancy centers. It evaluates single, biexponential, and stretched exponential models for fitting T1 curves. The study introduces techniques like pulse fitting and bootstrap to reduce noise and presents a rolling window method to analyze temporal evolution. By examining various gadolinium concentrations in chemical samples, it finds that stretched and biexponential fits better differentiate concentrations, particularly at higher levels. This research provides insights into optimizing data processing in quantum sensing applications.
