Description

Error-corrected quantum metrology for ultra-sensitive force sensing. This project seeks to answer a critical question in metrology: How much can quantum error correction improve quantum metrology beyond state-of-the-art using imperfect devices in noisy environments? This research aims to establish novel error-corrected quantum metrology protocols and demonstrate them on real quantum devices to achieve unprecedented performances in force sensing. The approach leverages an innovative hardware-efficient encoding scheme initially developed for quantum computing to significantly advance metrology. This work promises transformative metrology technologies with unmatched sensitivity and will deliver impacts in spectroscopy, fault-tolerant quantum computing, and the search for new physics, such as dark matter..
