Derives tight Holevo CRB for realistic linear sensors showing hierarchy with standard bounds and proposes readout improving LIGO rates by 25%.
A continuous-mode quantum optics theory unifies standard quantum limits for optical frequency division and dual-comb spectroscopy and outlines routes to engineered quantum enhancement.
A squeezed-vacuum interferometer with nonlinear phase estimation achieves Heisenberg scaling in the lossless limit, sub-SQL sensitivity under noise, and the first experimental quantum-optimal Bayesian signal estimation in a balanced interferometer.
Derives a generalized Schawlow-Townes linewidth limit for feedback oscillators that can be saturated by bad-cavity devices or surpassed via quantum engineering such as atomic spin squeezing.
