Quantum sensing and measurement devices are reaching a new level of accuracy for high-precision measurements, allowing detection of the most minute changes in magnetic, electric, and strain fields, gravity, and time. In this talk, I will present an overview of how integrated photonic and nanophotonic devices utilize entanglement to improve measurement accuracy and sensitivity. Examples will include the development of ultrabright and ultra-efficient quantum light sources as resources for sensors, integrated photonic magnetometry with exquisite sensitivity that can be further enhanced with squeezing, and strain sensors based on optomechanical modulation of quantum emitters via surface acoustic wave resonators.
The AlGaAsOI material platform offers great promise as a source of quantum states of light that can be utilized for enhanced sensing and metrology beyond the standard quantum limit. Here we focus on preliminary results from AlGaAsOI microring resonator sources that demonstrate a 1000-fold improvement in the brightness of entangled photon pairs compared to state-of-the-art chip-scale sources. The source maintains high single photon purity < 99% and time-energy entanglement visibility < 95%.
