A fully Gaussian quantum Stein's lemma
Filippo Girardi, Jacopo Rizzo, Leah Turner +2
A central yet mysterious problem in quantum information is the asymptotic distinguishability of quantum states under restricted measurements. Here we look at asymptotic asymmetric…
Passive optical superresolution at the quantum limit
A. I. Lvovsky, Michael R. Grace, Saikat Guha +3
For more than a century, the diffraction limit has defined the resolution achievable by passive optical imaging systems. Although some resolution improvement can be gained through…
Optimal Discrimination of Gaussian States by Gaussian Measurements
Leah Turner, Ludovico Lami, Madalin Guta +1
Are Gaussian measurements enough to distinguish between Gaussian states? Here, we tackle this question by focusing on the max-relative entropy as an operational distinguishability…
Quantum Limits of Passive Optical Surface Metrology and Defect Detection
Jernej Frank, George Brumpton, Tommaso Tufarelli +2
We develop a quantum statistical framework for passive optical surface metrology. Modelling a surface as an incoherent ensemble of point emitters imaged through a diffraction-limit…
Gravitational Decoherence Estimation in Optomechanical Systems
Leonardo A. M. Souza, Olimpio P. de Sá Neto, Enrico Russo +2
We develop a comprehensive quantum estimation framework to quantify how precisely gravitationally induced decoherence can be inferred in optomechanical systems, using single-mode G…
Equilibrium thermometry in the multilevel quantum Rabi model
Tabitha Doicin, Luis A. Correa, Jonas Glatthard +2
The temperature sensitivity of a probe in equilibrium can be gauged by its thermal quantum Fisher information (QFI). It is known that probes exhibiting degeneracy in their energy-l…
