TITLE: Optimal Control for Quantum Sensing with Spin Ensembles

ABSTRACT: Quantum sensors are an active field of research that take advantage of properties of quantum mechanics such as superposition and entanglement in order to perform certain measurements and oftentimes beat classical limits. This proposal focuses on the simulation of ensembles of quantum spins and the collective control with shaped magnetic fields. With immediate uses in electron paramagnetic resonance spectroscopy this proposal will look to numerically optimize magnetic field pulse shapes with the purpose of measuring the ensemble's spectrum. With an ensemble of coupled spins, these numerically optimized pulse shapes lead to the determination of the radial distance between the pairs. Finally, this work will look to optimize control of an entangled many-body state for quantum metrology beyond the shot noise limit.
