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 ...
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 ...
Optical magnetic detection of single-neuron action potentials using quantum defects in diamond
(Proceedings of the National Academy of Sciences, 2016)
Magnetic fields from neuronal action potentials (APs) pass largely unperturbed through biological tissue, allowing magnetic measurements of AP dynamics to be performed extracellularly or even outside intact organisms. To ...
