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 ...
Repetitive Readout of a Single Electronic Spin via Quantum Logic with Nuclear Spin Ancillae
(American Association for the Advancement of Science (AAAS), 2009)
Robust measurement of single quantum bits plays a key role in the realization of quantum computation and communication as well as in quantum metrology and sensing. We have implemented a method for the improved readout of ...
