Curator's Take
This article highlights a fundamental advancement in quantum sensing that could significantly improve our ability to measure physical quantities with unprecedented precision. Quantum sensing represents one of the most commercially viable near-term applications of quantum technology, already showing promise in fields like medical imaging, navigation systems that don't rely on GPS, and detecting gravitational waves. The enhancement of entanglement-based sensing schemes is particularly exciting because it demonstrates how quantum mechanics can provide genuine advantages over classical measurement techniques, potentially enabling detection of incredibly weak signals that would otherwise be impossible to observe. This work contributes to the growing momentum in quantum sensing, which many experts consider the quantum technology most likely to achieve widespread practical deployment in the next decade.

Summary
Over the past decades, quantum scientists have introduced various technologies that operate leveraging quantum mechanical effects, including quantum sensors, computers and memory devices. Most of these technologies leverage entanglement, a quantum phenomenon via which two or more particles become intrinsically linked and share a unified quantum state, irrespective of the distance between them.
