Coupling of NV Centers to Photonic Crystal Nanobeams in Diamond
(American Chemical Society (ACS), 2013)
The realization of efficient optical interfaces for solid-state atom-like systems is an important problem in quantum science with potential applications in quantum communications and quantum information processing. We ...
Integrated Diamond Networks for Quantum Nanophotonics
(American Chemical Society (ACS), 2012)
We demonstrate an integrated nanophotonic network in diamond, consisting of a ring resonator coupled to an optical waveguide with grating in- and outcouplers. Using a nitrogen-vacancy color center embedded inside the ring ...
Nanoscale magnetic imaging of a single electron spin under ambient conditions
(Nature Publishing Group, 2013)
The detection of ensembles of spins under ambient conditions has revolutionized the biological, chemical and physical sciences through magnetic resonance imaging1 and nuclear magnetic resonance2, 3. Pushing sensing ...
Magnetic Field Imaging with Nitrogen-Vacancy Ensembles
(Institute of Physics, 2011)
We demonstrate a method of imaging spatially varying magnetic fields using a thin layer of nitrogen-vacancy (NV) centers at the surface of a diamond chip. Fluorescence emitted by the two-dimensional NV ensemble is detected ...
Coherence of Nitrogen-Vacancy Electronic Spin Ensembles in Diamond
(American Physical Society, 2010)
We present an experimental and theoretical study of electronic spin decoherence in ensembles of nitrogen-vacancy (NV) color centers in bulk high-purity diamond at room temperature. Under appropriate conditions, we find ...
A Robust Scanning Diamond Sensor for Nanoscale Imaging with Single Nitrogen-Vacancy Centres
(Nature Publishing Group, 2012)
The nitrogen-vacancy defect centre in diamond has potential applications in nanoscale electric and magnetic-field sensing, single-photon microscopy, quantum information processing and bioimaging. These applications rely ...
Properties of Nitrogen-Vacancy Centers in Diamond: The Group Theoretic Approach
(Institute of Physics, 2011)
We present a procedure that makes use of group theory to analyze and predict the main properties of the negatively charged nitrogen-vacancy (NV) center in diamond. We focus on the relatively low temperature limit where ...
Single-Color Centers Implanted in Diamond Nanostructures
(Institute of Physics Publishing, 2011)
The development of material-processing techniques that can be used to generate optical diamond nanostructures containing a single-color center is an important problem in quantum science and technology. In this work, we ...
