Private capacity of quantum channels is not additive.

TL;DR: It is concluded for the first time that the classical private capacity is nonadditive: in this construction even the quantum capacity of the tensor product of two channels can be greater than the sum of their individual classical private capacities.
Journal ArticleDOI

Robustness of Quantum Markov Chains

TL;DR: It is shown that for tri-partite quantum states the quantum conditional information is always a lower bound for the minimum relative entropy distance to a quantum Markov chain state, but the distance can be much greater; indeed the two quantities can be of different asymptotic order and may even differ by a dimensional factor.
Journal ArticleDOI

Estimating quantum chromatic numbers

TL;DR: The tracial rank of a graph is a parameter that gives a lower bound for the commuting quantum chromatic number and parallels the projective rank, and it is multiplicative.
Journal ArticleDOI

Distilling common randomness from bipartite quantum states

TL;DR: A single-letter formula for the optimal tradeoff between the extracted common randomness and classical communication rate is obtained for the special case of classical-quantum correlations.
Journal ArticleDOI

Generalized laws of thermodynamics in the presence of correlations.

TL;DR: In this article, the authors exploit the connection between information and physics, and introduce a consistent redefinition of heat dissipation by systematically accounting for the information flow from system to bath in terms of the conditional entropy.
