Quantum Physics arXiv:2605.21702 (quant-ph) [Submitted on 20 May 2026] Title:Journey in quantum metrology and sensing from foundations to applications: a review Authors:Priya Ghosh, Tanoy Kanti Konar, Debraj Rakshit, Aditi Sen De, Ujjwal Sen View a PDF of the paper titled Journey in quantum metrology and sensing from foundations to applications: a review, by Priya Ghosh and 4 other authors View PDF Abstract:We present a review on quantum metrology and sensing, from its foundations to current applications. Highlights of the review include consideration of both frequentist and Bayesian approaches to parameter estimation; single as well as multiparameter estimation; estimation for different encoding processes comprising unitary as well as noisy channels, quantum thermometry, and channels involving indefinite causal order; different estimation strategies incorporating also recent advances like quantum error correction-aided methods and reservoir engineering; usefulness of quantum Fisher information to detect resources; applications of quantum metrology in diverse arenas covering quantum many-body sensors, sensing protocols in atomic ensembles, atom-photon systems, and continuous-variable systems, quantum imaging, quantum illumination, atomic clocks and atom interferometry, etc; and experimental realizations of quantum sensors in different physical platforms.
