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, ...
Environment-Assisted Precision Measurement
(American Physical Society, 2011)
We describe a method to enhance the sensitivity of precision measurements that takes advantage of the environment of a quantum sensor to amplify the response of the sensor to weak external perturbations. An individual qubit ...
Coherence And Control Of Quantum Registers Based On Electronic Spin In A Nuclear Spin Bath
(American Physical Society, 2009)
We consider a protocol for the control of few-qubit registers comprising one electronic spin embedded in a nuclear spin bath. We show how to isolate a few proximal nuclear spins from the rest of the bath and use them as ...
Coherence of an Optically Illuminated Single Nuclear Spin Qubit
(American Physical Society, 2008)
We investigate the coherence properties of individual nuclear spin quantum bits in diamond [Dutt et al., Science, 316, 1312 (2007)] when a proximal electronic spin associated with a nitrogen-vacancy (NV) center is being ...
