All-Optical Sensing of a Single-Molecule Electron Spin
(American Chemical Society (ACS), 2014)
We demonstrate an all-optical method for magnetic sensing of individual molecules in ambient conditions at room temperature. Our approach is based on shallow nitrogen-vacancy (NV) centers near the surface of a diamond ...
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 ...
Magnetic Resonance Detection of Individual Proton Spins Using Quantum Reporters
(American Physical Society (APS), 2014)
We demonstrate a method of magnetic resonance imaging with single nuclear-spin sensitivity under ambient conditions. Our method employs isolated electronic-spin quantum bits (qubits) as magnetic resonance “reporters” on ...
