    摘要: In an exemplary embodiment, a structure comprises a plurality of deterministically positioned optically active defects, wherein each of the plurality of deterministically positioned optically active defects has a linewidth within a factor of one hundred of a lifetime limited linewidth of optical transitions of the plurality of deterministically positioned optically active defects, and wherein the plurality of deterministically positioned optically active defects has an inhomogeneous distribution of wavelengths, wherein at least half of the plurality of deterministically positioned optically active defects have transition wavelengths within a less than 8 nm range. In a further exemplary embodiment, method of producing at least one optically active defect comprises deterministically implanting at least one ion in a structure using a focused ion beam; heating the structure in a vacuum at a first temperature to create at least one optically active defect; and heating the structure in the vacuum at a second temperature to remove a plurality of other defects in the structure, wherein the second temperature is higher than the first temperature.

    摘要: Systems and methods are disclosed for a pulse sequence that reduces disorder and/or interaction effects in spin systems. A protocol can be used to design a pulse sequence that includes altering the frame orientation of the spin system with each electromagnetic pulse in the pulse sequence. The frame orientations during the sequence can conform to certain conditions. The number positive rotations along each axis can be the same as the number negative rotations along the respective axis. The number of rotations along one axis should be the same as the number of rotations along the other axes.

    摘要: According to some embodiments, a method for quantum metrology using these stable non-equilibrium states of quantum matter, such as many-body quantum spin systems, is disclosed. The approach can utilize quantum correlations in such many-body quantum spin systems stabilized by strong interactions and periodic driving for reduction of noise. As an example, disclosed is an exemplary protocol to perform Floquet enhanced measurements of an oscillating magnetic field in Ising-interacting spin systems. The approaches described herein allow for circumvention of the interaction-induced decoherence associated with high density spin ensembles and is robust to the presence of noise and imperfections. The protocol is applicable to nanoscale magnetic sensing and other precision measurements.

    摘要: Systems and methods are disclosed for optically entangling distinguishable qubits. A system can include a first qubit having an optical transition at a first qubit frequency, a second qubit having an optical transition at a second qubit frequency, and a light source producing a first light beam having at least a first frequency. An interferometer can be configured to convert the first light beam into at least one second light beam, to provide the at least one second light beam to the first qubit and the second qubit, and to provide an output light signal. The interferometer can include a first optical modulator that converts the first light beam into the at least one second light beam, and a second optical modulator that produces the output light signal from the at least one second light beam.
