Although quantum sensors offer potentially better sensitivity than classical sensors, they are bulky and often require cooling to cryogenic temperatures or operation in vacuum. Here we propose a technical realization of a quantum sensor for magnetic field detection based on nitrogen-vacancy (NV) centers in diamond, which is compatible with miniaturization and offers potential sub-picotesla sensitivity. The miniaturization is based on recently developed electric readout of the NV center electron spin resonance. Our engineering platform allows to use diamond chip as a portable magnetic field sensor. We have designed and tested a miniaturized prototype and describe all key components for technical miniaturization. We achieved a power consumption down to 3.5 W, a weight of the fully integrated sensor of only 27g and small dimensions of 45 x 25 x 25 mm including all driving and readout components. We have proved the chip functionality in vacuum and explored its thermal behavior. The system will be further used for on-board stratospheric balloon experiment. The miniaturized sensor we developed has potential applications in a wide range of fields including navigation, bio-signal measurement, material analysis or space weather monitoring and planetary observation. | Keywords: | Diamond; NV centers; magnetometry; quantum sensing; Photocurrent Detection of Magnetic Resonance; miniaturization | Document URI: | http://hdl.handle.net/1942/28350 | Link to publication/dataset: | https://iafastro.directory/iac/paper/id/47157/summary/ | ISBN: | 9781510881655 | Rights: | 2018 by the International Astronautical Federation (IAF).
