Abstract

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 ones with "superquantum" correlations. A strengthened version of the quantum no-broadcasting theorem follows, and its proof is significantly simpler than existing proofs of the no-broadcasting theorem.

摘要

我们证明了无广播定理的一个广义版本，它适用于本质上任何满足无信号准则的非经典有限维概率模型，包括具有“超量子”关联的模型。由此得出量子无广播定理的一个强化版本，并且其证明比无广播定理的现有证明要简单得多。
