- Abstract summary: We propose and demonstrate remote quantum sensing using a chip-scale atomic vapor cell.
Specifically, we remotely interrogate mm-scale micromachined vapor cells, and measure the ambient Earth's magnetic field at a standoff distance of 10 meters.
We provide a novel toolset to measure and map arbitrary, remote, and hard to access magnetic field in unshielded environments with high sensitivity and spatial resolution.

- Abstract: Quantum sensing is an ever-evolving research field describing the use of a
quantum phenomenon to perform measurement of a physical quantity. Amongst
different types of quantum sensors, atomic vapor-based quantum effects are
extensively used to measure quantities such as time, velocity, acceleration,
and electric and magnetic fields. Here, we propose and demonstrate remote
quantum sensing using a chip-scale atomic vapor cell. Specifically, we remotely
interrogate mm-scale micromachined vapor cells, and measure the ambient Earth's
magnetic field at a standoff distance of ~10 meters and a sensitivity of ~1
pT/Hz^0.5 . Simultaneously we are able measure the distance between micro-cell
and the interrogating system by means of time-of-flight measurements, thus
correlating between position and magnetic field. Consequently, we provide a
novel toolset to measure and map arbitrary, remote, and hard to access magnetic
field in unshielded environments with high sensitivity and spatial resolution,
paving the way to a variety of novel applications in diverse fields such as
medicine, communication, defense, space-exploration, and quantum technologies.

Local detection of magnetic fields is crucial for characterizing nano- and micro-materials.

A physical model for such a randomly oriented nanodiamond ensemble (NDE) is available, but the complexity of actual experimental conditions still limits the accuracy of deducing magnetic fields.
Here, we demonstrate magnetic field imaging with high accuracy of 1.8 $mu$T combining NDE and machine learning without any physical models.
