Overview

This computational study reveals decoherence mechanisms in the boron vacancy center, indicating optimal magnetic field ranges for enhanced sensor performance.

Key Points

  • Decoherence limits the sensitivity of boron vacancy center-based quantum sensors in hexagonal boron nitride.
  • Five distinct magnetic field regions influence decoherence mechanisms involving nuclear spin interactions.
  • The optimal coherence time of 1-20 microseconds was observed in the moderate magnetic field of 180-350 mT.
  • Investigating zero-field splitting and hyperfine coupling enhances understanding of boron vacancy center performance.
