Jincheng Zhang
Abstract
This paper explores the development and potential of quantum sensors utilizing multi-variable measurement. The core concept revolves around leveraging the quantum coherence inherent in quantum sensors to simultaneously measure multiple physical quantities. This is achieved through the design of entangled sensor networks, where the state of one sensor provides information about the states of all interconnected sensors. This approach represents a significant advancement in the field of quantum sensing, offering the possibility of enhanced sensitivity and reduced measurement complexity for applications requiring the simultaneous determination of multiple parameters. The theoretical framework presented here outlines the fundamental principles and explores potential architectures, highlighting the advantages and challenges associated with this technology. We focus on the mathematical underpinnings of entangled sensor systems and the extraction of information from correlated quantum states. ---
