Ultraprecise Nanoscale Integrated Quantum Entangled Sensors (UNIQUES)
Abstract
In this Project, we will develop ultraprecise nanoscale integrated quantum entanglement sensors (UNIQUES) to boost the sensitivity of measuring, e.g., radiofrequency (RF), mechanical, and thermal signals for critical naval applications by improving the signal-to-noise ratio of measuring small phase modulation in an array of Mach-Zehnder interferometers (MZI) composed of an array of photonic integrated nanoscale transducers. The quantum-enhanced sensor will enable processing with a much smaller integration time and power level than a classical RF photonic receiver while obtaining a comparable or higher fidelity of signal detection. In this Project, we will:(1) experimentally demonstrate a proof-of-concept UNIQUES system first in a bulk-optics setup and then in an integrated quantum photonic platform to show a 5x signal-to-noise ratio (SNR) improvement in measurement tasks such as field amplitude and phase sensing;(2) build an integrated on-demand programmable CVMP entanglement source and a nanoscale transducer array (for scalable and low-cost operations); and(3) implement UNIQUES and demonstrate chip-scale entanglement-enhanced sensing for weak RF signals with a 5x SNR improvement over classical schemes.
