摘要: A method for probing the properties of nanoscale materials, such as 2D materials or proteins, via nanometer-scale nuclear quadrupole resonance (NQR) spectroscopy using individual atom-like impurities in diamond. Coherent manipulation of shallow nitrogen-vacancy (NV) color centers enables the probing of the NQR spectrum of nanoscale ensembles of nuclear spins. Measuring the NQR spectrum at different magnetic field orientations and magnitudes and fitting to a theoretical model allows for the extraction of atomic structural properties of the material with nanoscale resolution.

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: Systems and methods are disclosed for preparing and evolving atomic defects in diamond. Silicon vacancy spins may be cooled to temperatures equal to or below 500 mK to reduce the influence of phonons. The cooling, manipulation, and observation systems may be designed to minimize added heat into the system. A CPMG sequence may be applied to extend coherence times. Coherence times may be extended, for example, to 13 ms.

摘要: Systems and methods are disclosed for making a quantum network node. A plurality of scoring function F values are calculated for an array of at least two photonic crystal cavity unit cells, each having a lattice constant a and a hole having a length Hx and a width Hy. A value of a, a value of Hx, and a value of Hy are selected for which a scoring function value is at a maximum. A waveguide region and the array of at least two photonic crystal cavity unit cells based on the selected values are formed on a substrate. At least one ion between a first photonic crystal cavity unit cell and a second photonic crystal cavity unit cell are implanted and annealed into a quantum defect. A coplanar microwave waveguide is formed on the substrate in proximity to the array of at least two photonic crystal cavity unit cells.

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.
