Non-Linear Strong Data-Processing for Quantum Hockey-Stick Divergences
Theshani Nuradha, Ian George, Christoph Hirche
Data-processing is a desired property of classical and quantum divergences and information measures. In information theory, the contraction coefficient measures how much the distin…
Query complexities of quantum channel discrimination and estimation: A unified approach
Zixin Huang, Johannes Jakob Meyer, Theshani Nuradha +1
The goal of quantum channel discrimination and estimation is to determine the identity of an unknown channel from a discrete or continuous set, respectively. The query complexity o…
Query Complexity of Classical and Quantum Channel Discrimination
Theshani Nuradha, Mark M. Wilde
Quantum channel discrimination has been studied from an information-theoretic perspective, wherein one is interested in the optimal decay rate of error probabilities as a function…
Quantum Doeblin Coefficients: Interpretations and Applications
Ian George, Christoph Hirche, Theshani Nuradha +1
In classical information theory, the Doeblin coefficient of a classical channel provides an efficiently computable upper bound on the total-variation contraction coefficient of the…
Measured Hockey-Stick Divergence and its Applications to Quantum Pufferfish Privacy
Theshani Nuradha, Vishal Singh, Mark M. Wilde
The hockey-stick divergence is a fundamental quantity characterizing several statistical privacy frameworks that ensure privacy for classical and quantum data. In such quantum priv…
