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…
Looking down the rabbit hole: Towards quantum optimal estimation of surface roughness
Quentin Muller, Tommaso Tufarelli, Madalin Guta +3
Surface roughness is an important quantity to many engineering and precision manufacturing disciplines. In this paper we investigate the problem of estimating the root-mean-square…
The rate of purification of quantum trajectories
Maël Bompais, Nina H. Amini, Juan P. Garrahan +1
We investigate the behavior of quantum trajectories conditioned on measurement outcomes. Under a condition related to the absence of so-called dark subspaces, Kümmerer and Maassen…
All non-Gaussian states are advantageous for channel discrimination: Robustness of non-convex continuous variable quantum resources
Leah Turner, Madalin Guta, Gerardo Adesso
Which quantum phenomena are advantageous for information processing tasks? By classifying quantum states as resourceful versus non-resourceful, or free, the mathematical formalism…
Estimating quantum Markov chains using coherent absorber post-processing and pattern counting estimator
Federico Girotti, Alfred Godley, Mădălin Guţă
We propose a two step strategy for estimating one-dimensional dynamical parameters of a quantum Markov chain, which involves quantum post-processing the output using a coherent qua…
Bounds on Fluctuations of First Passage Times for Counting Observables in Classical and Quantum Markov Processes
George Bakewell-Smith, Federico Girotti, Mădălin Guţă +1
We study the statistics of first passage times (FPTs) of trajectory observables in both classical and quantum Markov processes. We consider specifically the FPTs of counting observ…
