Jan Głowacki

AI总结:

本文系统研究算子值函数关于正算子值测度的积分,并利用这些工具定义一般齐性空间上量子参考系的相对化映射,证明其是收缩量子信道,对可定位框架是单射,对锐框架是乘性的。

摘要:

本文首次系统研究了由算子值函数关于正算子值测度的积分产生的算子,并利用这些工具为定义在一般齐性空间上的量子参考系(QRF)提供了相对化映射(Yen)。首先研究了算子值积分的性质,然后将其用于定义一般的相对化映射并展示其性质。这里给出的相对化映射是基于局部紧第二可数拓扑群的任意齐性空间上的QRF(协方差系统)定义的,并证明它们是收缩量子信道,对可定位(范数-1性质)框架是单射,对锐框架(PVM)是乘性的,从而扩展了现有结果。

英文摘要:

This paper initiates a systematic study of operators arising as integrals of operator-valued functions with respect to positive operator-valued measures and utilizes these tools to provide relativization maps (Yen) for quantum reference frames (QRFs) defined on general homogeneous spaces. Properties of operator-valued integration are first studied and then employed to define general relativization maps and show their properties. The relativization maps presented here are defined for QRFs (systems of covariance) based on arbitrary homogeneous spaces of locally compact second countable topological groups and are shown to be contracting quantum channels, injective for localizable (norm-1 property) frames and multiplicative for the sharp ones (PVMs), extending the existing results.
