Abstract: Systems and methods are disclosed for increasing a nuclear spin polarization of a target compound. In accordance with such systems and methods, a first non-thermal equilibrium nuclear spin polarization can be imparted to at least one source atom of a source compound, the source atom having a nuclear gyromagnetic ratio of at least 12 megahertz per tesla (MHz/T). A first solution can be obtained that includes the source compound and a target compound. The at least one source atom can be present in a source concentration of at least 0.1 molar (M) in the first solution. A second non-thermal equilibrium nuclear spin polarization of at least 0.01% can be imparted to the at least one target atom of the target compound via a nuclear Overhauser effect (NOE) transfer of the first non-thermal equilibrium nuclear spin polarization to the at least one target atom.

Abstract: Microwave resonator readout of the cavity-spin interaction between a spin defect center ensemble and a microwave resonator yields fidelities that are orders of magnitude higher than is possible with optical readouts. In microwave resonator readout, microwave photons probe a microwave resonator coupled to a spin defect center ensemble subjected to a physical parameter to be measured. The physical parameter shifts the spin defect centers' resonances, which in turn change the dispersion and/or absorption of the microwave resonator. The microwave photons probe these dispersion and/or absorption changes, yielding a measurement with higher visibility, lower shot noise, better sensitivity, and higher signal-to-noise ratio than a comparable fluorescence measurement. In addition, microwave resonator readout enables coherent averaging of spin defect center ensembles and is compatible with spin systems other than nitrogen vacancies in diamond.
