论文摘要
没有广播定理是量子信息理论中最基本的结果之一。它可以保证，基于窃听和复制量子信息的任何量子协议的最简单攻击是不可能的。由于非广播定理的基本重要性，必须了解这种限制的确切界限。我们通过限制我们想要广播和限制我们用于测试广播的测量集的一组状态来概括广播的标准定义。我们表明，在某些调查的案例中，广播等效于通勤性，而在其他情况下则不需要通勤。
No-broadcasting theorem is one of the most fundamental results in quantum information theory; it guarantees that the simplest attacks on any quantum protocol, based on eavesdropping and copying of quantum information, are impossible. Due to the fundamental importance of the no-broadcasting theorem, it is essential to understand the exact boundaries of this limitation. We generalize the standard definition of broadcasting by restricting the set of states which we want to broadcast and restricting the sets of measurements which we use to test the broadcasting. We show that in some of the investigated cases broadcasting is equivalent to commutativity, while in other cases commutativity is not necessary.
