1. A method of quantum sensing, comprising:
depositing a sample volume onto an ensemble of quantum defects;
hyperpolarizing spins in the sample volume;
performing a sensing sequence; and
reading out information regarding electronic spin states of the quantum defects in the ensemble of quantum defects, which sense the hyperpolarized spins in the sample volume.
