Convergence rates for the quantum central limit theorem
Simon Becker, Nilanjana Datta, Ludovico Lami +1
Various quantum analogues of the central limit theorem, which is one of the cornerstones of probability theory, are known in the literature. One such analogue, due to Cushen and Hu…
Strong Converse for Classical-Quantum Degraded Broadcast Channels
Hao-Chung Cheng, Nilanjana Datta, Cambyse Rouzé
We consider the transmission of classical information through a degraded broadcast channel, whose outputs are two quantum systems, with the state of one being a degraded version of…
Strong converse bounds in quantum network information theory: distributed hypothesis testing and source coding
Hao-Chung Cheng, Nilanjana Datta, Cambyse Rouzé
We consider a distributed quantum hypothesis testing problem with communication constraints, in which the two hypotheses correspond to two different states of a bipartite quantum s…
Eventually entanglement breaking Markovian dynamics: structure and characteristic times
Eric P. Hanson, Cambyse Rouzé, Daniel Stilck França
We investigate entanglement breaking times of Markovian evolutions in discrete and continuous time. In continuous time, we characterize which Markovian evolutions are eventually en…
Quantum reverse hypercontractivity: its tensorization and application to strong converses
Salman Beigi, Nilanjana Datta, Cambyse Rouzé
In this paper we develop the theory of quantum reverse hypercontractivity inequalities and show how they can be derived from log-Sobolev inequalities. Next we prove a generalizatio…
Relating relative entropy, optimal transport and Fisher information: a quantum HWI inequality
Cambyse Rouzé, Nilanjana Datta
Quantum Markov semigroups characterize the time evolution of an important class of open quantum systems. Studying convergence properties of such a semigroup, and determining concen…
