Overview

First-principles analysis reveals how magnetic fields affect V B − spin decoherence in h-BN, suggesting better qubit design.

Key Points

  • Dominant decoherence changes occur at a transition boundary of 0.502 T for h‐10 B14 N, improving spin qubit performance.
  • Below the transition boundary, decoherence is governed by independent nuclear spin dynamics, enhancing qubit stability.
  • First-principles quantum many-body simulations across various isotopic variants provide insights into nuclear interactions.
  • The findings highlight the significance of nuclear spin baths in V B − spin decoherence for future qubit designs.
