Room-temperature magnetic gradiometry with fiber-coupled nitrogen-vacancy centers in diamond.

چکیده
Differential optical detection of a magnetic resonance induced in nitrogen-vacancy (NV) centers in diamond is shown to enable a high-spatial-resolution room-temperature magnetic-field gradiometry on a fiber platform. An ultracompact design of this fiber-based solid-state magnetic gradiometer is achieved by integrating an NV-diamond magnetic sensor with a two-fiber opto-microwave interface, which couples NV centers to microwave and optical fields, used to resonantly drive and interrogate the spin of NV centers.

Decoherence - protected transitions of nitrogen vacancy centers in 99 % 13 C diamond
Nitrogen vacancy (NV−) color centers in diamond are a prime candidate for use in quantum information devices, owing to their spin-1 ground state, straightforward optical initialization and readout, and long intrinsic coherence times in a room-temperature solid. While the 13C nuclear spin is often a dominant source of magnetic noise, we observe transitions between electron-nuclear hyperfine stat...
متن کاملLow-temperature tapered-fiber probing of diamond nitrogen-vacancy ensembles coupled to GaP microcavities
In this work, we present a platform for testing the device performance of a cavity–emitter system, using an ensemble of emitters and a tapered optical fiber. This method provides high-contrast spectra of the cavity modes, selective detection of emitters coupled to the cavity and an estimate of the device performance in the single-emitter case. Using nitrogen-vacancy (NV) centers in diamond and ...
متن کاملLow temperature studies of the excited-state structure of negatively charged nitrogen-vacancy color centers in diamond.
We report a study of the 3E excited-state structure of single negatively charged nitrogen-vacancy (NV) defects in diamond, combining resonant excitation at cryogenic temperatures and optically detected magnetic resonance. A theoretical model is developed and shows excellent agreement with experimental observations. In addition, we show that the two orbital branches associated with the 3E excite...
متن کاملPolarization and readout of coupled single spins in diamond.
We study the coupling of a single nitrogen-vacancy center in diamond to a nearby single nitrogen defect at room temperature. The magnetic dipolar coupling leads to a splitting in the electron spin resonance frequency of the nitrogen-vacancy center, allowing readout of the state of a single nitrogen electron spin. At magnetic fields where the spin splitting of the two centers is the same, we obs...
متن کاملHigh - precision electron - spin sensing with ensembles of nitrogen - vacancy centers in diamond
This thesis describes physical background and an experimental realization of a bulk diamond magnetic field and temperature sensor. The sensing is done using continuous-wave electronspin resonance spectra of nitrogen-vacancy centers in diamond. Experiments were performed using a light-trapping diamond waveguide sample, with which we estimate to address 10" nitrogen-vacancy centers simultaneously...
