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 ...
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 ...
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 ...
Enhanced metrology using preferential orientation of nitrogen-vacancy centers in diamond
(American Physical Society (APS), 2012)
We demonstrate preferential orientation of nitrogen-vacancy (NV) color centers along two of four possible crystallographic axes in diamonds grown by chemical vapor deposition on the {100} face. We identify the relevant ...
Suppression of spin-bath dynamics for improved coherence of multi-spin-qubit systems
(Springer Nature, 2012)
Multi-qubit systems are crucial for the advancement and application of quantum science. Such systems require maintaining long coherence times while increasing the number of qubits available for coherent manipulation. For ...
Coherent, Mechanical Control of a Single Electronic Spin
(American Chemical Society (ACS), 2012)
We demonstrate coherent quantum control of a single spin driven by the motion of a mechanical resonator. The motion of a mechanical resonator is magnetically coupled to the electronic spin of a single nitrogen-vacancy ...
Enhanced solid-state multispin metrology using dynamical decoupling
(American Physical Society (APS), 2012)
We use multipulse dynamical decoupling to increase the coherence lifetime (T2) of large numbers of nitrogen-vacancy (NV) electronic spins in room temperature diamond, thus enabling scalable applications of multispin quantum ...
Efficient photon detection from color centers in a diamond optical waveguide
(American Physical Society (APS), 2012)
A common limitation of experiments using color centers in diamond is the poor photon collection efficiency of microscope objectives due to refraction at the diamond interface. We present a simple and effective technique ...
Electromagnetically Induced Transparency with Noisy Lasers
(American Physical Society, 2009)
We demonstrate and characterize two coherent phenomena that can mitigate the effects of laser phase noise for Electromagnetically Induced Transparency (EIT): a laser-power-broadening-resistant resonance in the transmitted ...
