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 ...
Atom-like crystal defects: From quantum computers to biological sensors
(AIP Publishing, 2014)
Atomic-Scale Nuclear Spin Imaging Using Quantum-Assisted Sensors in Diamond
(American Physical Society (APS), 2015)
Nuclear spin imaging at the atomic level is essential for the understanding of fundamental biological phenomena and for applications such as drug discovery. The advent of novel nanoscale sensors promises to achieve the ...
A robust scanning diamond sensor for nanoscale imaging with single nitrogen-vacancy centres
(Nature Publishing Group, 2012)
Controllable atomic-scale quantum systems hold great potential as sensitive tools for nanoscale imaging and metrology . Possible applications range from nanoscale electric and magnetic field sensing to single photon ...
Spectroscopy of composite solid-state spin environments for improved metrology with spin ensembles.
(2012)
For precision coherent measurements with ensembles of quantum spins the relevant Figure-of Merit (FOM) is the product of polarized spin density and coherence lifetime, which is generally limited by the dynamics of the spin ...
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 ...
Gravitational wave detection with optical lattice atomic clocks
(American Physical Society (APS), 2016)
We propose a space-based gravitational wave (GW) detector consisting of two spatially separated, drag-free satellites sharing ultrastable optical laser light over a single baseline. Each satellite contains an optical lattice ...
Nanoscale NMR spectroscopy and imaging of multiple nuclear species
(Nature Publishing Group, 2015)
Nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI) provide non-invasive information about multiple nuclear species in bulk matter, with wide-ranging applications from basic physics and ...
Nuclear magnetic resonance detection and spectroscopy of single proteins using quantum logic
(American Association for the Advancement of Science (AAAS), 2016)
Nuclear magnetic resonance spectroscopy is a powerful tool for the structural analysis of organic compounds and biomolecules but typically requires macroscopic sample quantities. We use a sensor, which consists of two ...
NMR technique for determining the depth of shallow nitrogen-vacancy centers in diamond
(American Physical Society (APS), 2016)
We demonstrate a robust experimental method for determining the depth of individual shallow nitrogen-vacancy
(NV) centers in diamond with ∼1 nm uncertainty. We use a confocal microscope to observe single NV centers ...
