Hamiltonian estimation for NV centers
Built a cost-function driven random-field estimation loop for NV-center Hamiltonians and compared strong/weak coupling regimes.
Problem
Needed reliable NV-center Hamiltonians for state preparation without exhaustive calibration.
Approach
Simulated NV dynamics, swept candidate hyperfine parameters with a random-field strategy, and minimized a cost over measured traces to recover plausible Hamiltonians.
Outcome
Produced candidate Hamiltonians for strong- and weak-coupling cases used in follow-on state-preparation work and the capstone random-field study.
