Near-optimal performance of square-root measurement for general score functions and quantum ensembles
Hemant K. Mishra, Ludovico Lami, Mark M. Wilde
The Barnum-Knill theorem states that the optimal success probability in the multiple state discrimination task is not more than the square root of the success probability when the…
A Complete Characterization of Passive Unitary Normalizable (PUN) Gaussian States
Tiju Cherian John, Hemant K. Mishra, Saikat Guha
We provide a complete characterization of the class of multimode quantum Gaussian states that can be reduced to a tensor product of thermal states using only a passive unitary oper…
Converse bounds for quantum hypothesis exclusion: A divergence-radius approach
Kaiyuan Ji, Hemant K. Mishra, Milán Mosonyi +1
Hypothesis exclusion is an information-theoretic task in which an experimenter aims at ruling out a false hypothesis from a finite set of known candidates, and an error occurs if a…
