Abstract
Section titled āAbstractāPrecise knowledge of a quantum systemās Hamiltonian is a critical\npre-requisite for its use in many quantum information technologies. Here, we\nreport a method for the precise characterization of the non-secular part of the\nexcited-state Hamiltonian of an electronic-nuclear spin system in diamond. The\nmethod relies on the investigation of the dynamic nuclear polarization mediated\nby the electronic spin, which is currently exploited as a primary tool for\ninitializing nuclear qubits and performing enhanced nuclear magnetic resonance.\nBy measuring the temporal evolution of the population of the ground-state\nhyperfine levels of a nitrogen-vacancy center, we obtain the first direct\nestimation of the excited-state transverse hyperfine coupling between its\nelectronic and nitrogen nuclear spin. Our method could also be applied to other\nelectron-nuclear spin systems, such as those related to defects in silicon\ncarbide.\n
