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…
Universal proofs of entropic continuity bounds via majorization flow
Eric P. Hanson, Nilanjana Datta
We introduce a notion of majorization flow, and demonstrate it to be a powerful tool for deriving simple and universal proofs of continuity bounds for entropic functions relevant i…
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…
