论文摘要
我们提出了一个基于路径积分的量子理论的配方中正确的物理阳性条件的强烈阳性作为正确的物理阳性条件。我们扩展到BOES和NAVASCUES的无限系统工作，这表明在张量产品组成下关闭的一组系统中，强大的量子系统集合是最大的。我们进一步表明，强烈的量子系统集合是在张量产品组成下关闭的集合中最大的独特集。
We give an argument for strong positivity of the decoherence functional as the correct, physical positivity condition in formulations of quantum theory based fundamentally on the path integral. We extend to infinite systems work by Boes and Navascues that shows that the set of strongly positive quantum systems is maximal amongst sets of systems that are closed under tensor product composition. We show further that the set of strongly positive quantum systems is the unique set that is maximal amongst sets that are closed under tensor product composition.
