Nanophotonic approaches to atomic sensors
Abstract
Atom-based quantum sensing utilizes the discrete energy transitions of atomic electrons tomeasure physical quantities (including time, electromagnetic fields, and inertial motion) withunparalleled precision and accuracy. However, it is difficult to achieve similar sensingperformances on mobile platforms, largely due to implementation challenges associated with thesize and complexity of quantum sensing systems. Therefore, this field would greatly benefit fromtransformative engineering approaches to miniaturize and simplify sensor designs.The proposed work aims to improve the functionality and performance of atom-based sensors byimplementing nanoscale components with the requisite optical response to achieve efficient atomphotoninteractions. Recent advances in nanophotonics, most especially in the development ofdiffractive and metasurface components, provide a powerful set of tools and techniques that willbe adapted for operation in atom-based sensors under this program. The proposed technicalapproach consists of design and nanofabrication of integrated photonic components tailored foratomic systems, and demonstration of their integrability and performance benefits in low-noiseatomic magnetometers and sensitive atomic gravimeters.While atomic magnetometry and gravimetry will be the focus of this program, results of this workare intended to be applicable to other sensing modalities (including atomic clocks and gyroscopes).Beyond enabling more compact atomic sensor designs, a goal of this program is to achieveimproved understanding and control of fundamental atom-photon interactions. Moreover, closepartnership among the fields of photonics, material science, and atomic physics will be crucial forthe proposed development, and this multidisciplinary approach will likely continue to be keytowards future realization of fully integrated and scalable quantum sensing, computing, andnetworking instruments.
