Belief-invariant Equilibria in Games with Incomplete Information
TL;DR: In this paper, a general framework of belief-invariant communication equilibria is presented, which contains quantum correlations as special cases, and the theory of Bell inequalities is discussed.

Flexible constrained de Finetti reductions and applications
Cécilia Lancien,Andreas Winter +1 more
TL;DR: In this article, it was shown that in many quantum information applications, a more relaxed de Finetti reduction (i.e., only a matrix inequality between the symmetric state and one of de finetti form) is enough and that it leads to more concise and elegant arguments.
Journal ArticleDOI
Resource theory of unextendibility and nonasymptotic quantum capacity
TL;DR: In this paper, the authors introduce the resource theory of unextendibility as a relaxation of the resource theories of entanglement, and obtain nonasymptotic upper bounds on the rate at which quantum communication or entenglement preservation is possible over a finite number of uses of an arbitrary quantum channel assisted by $k$-extendible channels at no cost.

Strong converse for the capacity of quantum Gaussian channels
TL;DR: It is proved that a strong converse theorem holds for the classical capacity of all phase-insensitive bosonic Gaussian channels, when imposing a maximum photon number constraint on the inputs of the channel.
