Generalized no-broadcasting theorem.
We prove a generalized version of the no-broadcasting theorem, applicable to essentially any nonclassical finite-dimensional probabilistic model satisfying a no-signaling criterion, including onesExpand

Teleportation in General Probabilistic Theories
In a previous paper, we showed that many important quantum information-theoretic phenomena, including the no-cloning and no-broadcasting theorems, are in fact generic in all non-classicalExpand

Information Processing in Convex Operational Theories
In order to understand the source and extent of the greater-than-classical information processing power of quantum systems, one wants to characterize both classical and quantum mechanics as points inExpand

Cloning and Broadcasting in Generic Probabilistic Theories
We prove generic versions of the no-cloning and no-broadcasting theorems, applicable to essentially {\em any} non-classical finite-dimensional probabilistic model that satisfies a no-signalingExpand

Perspectivity and congruence in partial abelian semigroups
To any subset M of a partial abelian semigroup L, we associate a relation of perspectivity ~M, where a ~ M b if and only if there exists some element c G L such that a® c and c® b both exist andExpand

Degenerate fibres in the Stone-Cech compactification of the universal bundle of a finite group
Applied to a continuous surjection π: E → B of completely regular Hausdorff spaces E and B, the Stone-Cech compactification functor β yields a surjection βπ: βE → βB. For an n-fold covering map π, weExpand

Post-Classical Probability Theory
This chapter offers a brief introduction to what is often called the convex-operational approach to the foundations of quantum mechanics, and reviews selected results, mostly by ourselves andExpand

Ensemble Steering, Weak Self-Duality, and the Structure of Probabilistic Theories
In any probabilistic theory, we say that a bipartite state ω on a composite system ABsteers its marginal state ωB if, for any decomposition of ωB as a mixture ωB=∑ipiβi of states βi on B, thereExpand

Test Spaces and Orthoalgebras
In a long series of papers published in the 1970s and early 1980s, D. J. Foulis and C. H. Randall developed a conceptually simple, but very compelling semantics for quantum logics and otherwise basedExpand
