• Abstract: We experimentally demonstrate the integration of silicon-vacancy centers in nanodiamonds (SiV-NDs) with an optical nanofiber (ONF). We grow SiV-NDs on seed NDs dispersed on a quartz substrate using a microwave plasma-assisted chemical vapor deposition method. First, we search and characterize SiV-NDs on a quartz substrate using an inverted confocal microscope and an atomic force microscope (AFM). Subsequently, we pick up SiV-NDs from the quartz substrate and deposit them on the surface of a free-standing ONF using the AFM tip. The fluorescence emission spectrum, photon count rate, and intensity correlations for SiV-NDs are systematically measured.

  Pairs of entangled photons are a key resource for photonic quantum technologies. Despite the success in the demonstration of spontaneous parametric-down-conversion (SPDC), there are almost no works on spontaneous four-wave mixing (SFWM) SFWM can be implemented in any nanostructures, including isotropic and centrosymmetric ones.

  We present first-principles electronic structure calculations of color centers in ultrasmall nanodiamonds (USNDs) We find that the nitrogen-vacancy (NV-) can be stabilized in a negative charge state if the nanoparticles are terminated by fluorine, hydroxyl, and ether. Interestingly, the phonon renormalizations of single-particle energy levels found in arrays contribute to the charge stability of negatively charged NV centers.

  Transition metal dichalcogenide (TMD) single photon emitters offer numerous advantages to quantum information applications. Traditional materials used for the fabrication of nanoresonators, such as silicon or gallium phosphide (GaP), often require a high refractive index substrate. Here, we use nanoantennas (NAs) fabricated from multilayer TMDs, which allow complete flexibility with the choice of substrate.

  We conduct a detailed assessment of the surface oxide that forms in ambient conditions for transmon test devices patterned from a niobium film. In terms of structural analysis, we find that the Nb$ 1-2$O$_5$ region is semicrystalline in nature. We observe that amorphous regions are more likely to contain oxygen vacancies and exhibit weaker bonds between the niobium and oxygen atoms.

• Nanoscale Solid-State Nuclear Quadrupole Resonance Spectroscopy using Depth-Optimized Nitrogen-Vacancy Ensembles in Diamond [9.322875230001717]
  Nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) spectroscopy of bulk quantum materials have provided insight into phenomena such as quantum phase criticality, magnetism, and superconductivity. With the emergence of nanoscale 2-D materials with magnetic phenomena, inductively-detected NMR and NQR spectroscopy are not sensitive enough to detect the smaller number of spins in nanomaterials. The nitrogen-vacancy (NV) center in diamond has shown promise in bringing the analytic power of NMR and NQR spectroscopy to the nanoscale.

Our approach serves as a practical method to systematically characterize SPEs in hBN prior to integration in quantum photonics systems.
