Quantum-Enhanced Sensing based on Centralized and Distributed Entanglement
ORAL · Invited
Abstract
Entanglement, a unique quantum mechanical phenomenon with no classical equivalent, now fuels precision measurements by enabling sensors to surpass the classical limits dictated by inherent quantum fluctuations. In this talk, I will introduce two distinct quantum-enhanced sensing regimes that capitalize on entanglement to improve the measurement performance. The first leverages entanglement embedded in a frequency comb to reduce the integration time of a centralized dual-comb-spectroscopy system. The second harnesses entanglement across multiple sensors to improve the sensitivity and bandwidth of distributed radio-frequency and force measurements. We will showcase the advantages of both regimes over their classical counterparts and discuss prospects for scalable quantum-enhanced sensing technologies.
