    Exploring Novel Quantum Physics Using Ytterbium-171 in An Optical Cavity by Li, Zeyang

    Published 2023
    “…We also implement a time-reversal-based quantum metrology protocol. We demonstrate that this method benefits practical quantum metrology since it improves the signal-to-noise ratio by amplifying the signal rather than reducing the noise. …”

    Asymptotic optimality of twist-untwist protocols for Heisenberg scaling in atom-based sensing by T. J. Volkoff, Michael J. Martin

    Published 2022-03-01
    “…Twist-untwist protocols for quantum metrology consist of a serial application of (1) unitary nonlinear dynamics (e.g., spin squeezing or Kerr nonlinearity), (2) parameterized dynamics U(ϕ) (e.g., a collective rotation or phase space displacement), and (3) time reversed application of step 1. …”
