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 ...
Double Quantum Dots in Carbon Nanotubes
(American Physical Society, 2010)
We study the two-electron eigenspectrum of a carbon-nanotube double quantum dot with spin-orbit coupling. Exact calculations are combined with a simple model to provide an intuitive and accurate description of single-particle ...
Qubit Protection in Nuclear-Spin Quantum Dot Memories
(American Physical Society, 2009)
We present a mechanism to protect quantum information stored in an ensemble of nuclear spins in a semiconductor quantum dot. When the dot is charged the nuclei interact with the spin of the excess electron through the ...
Phonon cooling and lasing with nitrogen-vacancy centers in diamond
(American Physical Society (APS), 2013)
We investigate the strain-induced coupling between a nitrogen-vacancy impurity and a resonant vibrational mode of a diamond nanoresonator. We show that under near-resonant laser excitation of the electronic states of the ...
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 ...
Optomechanical Transducers for Long-Distance Quantum Communication
(American Physical Society, 2010)
We describe a new scheme to interconvert stationary and photonic qubits which is based on indirect qubit-light interactions mediated by a mechanical resonator. This approach does not rely on the specific optical response ...
Single-Photon Nonlinear Optics with Graphene Plasmons
(American Physical Society (APS), 2013)
We show that it is possible to realize significant nonlinear optical interactions at the few photon level in graphene nanostructures. Our approach takes advantage of the electric field enhancement associated with the ...
Scalable Architecture for a Room Temperature Solid-State Quantum Information Processor
(Nature Publishing Group, 2012)
The realization of a scalable quantum information processor has emerged over the past decade as one of the central challenges at the interface of fundamental science and engineering. Here we propose and analyse an ...
Imaging Mesoscopic Nuclear Spin Noise with a Diamond Magnetometer
(American Institute of Physics, 2010)
Magnetic resonance imaging can characterize and discriminate among tissues using their diverse physical and biochemical properties. Unfortunately, submicrometer screening of biological specimens is presently not possible, ...
Photon Sorters and QND Detectors Using Single Photon Emitters
(Institute of Physics Publishing, 2012)
We discuss a new method for realizing number-resolving and non-demolition photo detectors by strong coupling of light to individual single photon emitters, which act as strong optical non-linearities. As a specific application ...
