论文摘要
张量和跟踪概括，因此可以根据几乎任意的逻辑谓词对系统进行分配。人们可能会担心单位性，完全积极性，痕量保护，非信号因果关系，局部性和本地定位性在量子理论中标准的熟悉的相互关系被损害，因为系统的分配既是逻辑又动态的。实际上，这种相互关系贯穿了，尽管一种新的概念，一致性，但具有工具性。
Tensors and traceouts are generalised, so that systems can be partitioned according to almost arbitrary logical predicates. One might have feared that the familiar interrelations between the notions of unitarity, complete positivity, trace-preservation, non-signalling causality, locality and localizability that are standard in quantum theory be jeopardized as the partitioning of systems becomes both logical and dynamical. Such interrelations in fact carry through, although a new notion, consistency, becomes instrumental.
