算子代数形式中的量子测量问题与系统自描述

Quantum Measurement Problem and Systems Selfdescription in Operators Algebras Formalism

S. Mayburov

摘要:

系统自描述的信息论方法研究的量子测量问题,利用了任意信息系统信息获取的不完全性。所研究的测量系统模型由被测状态S、环境E和观测器$O$处理输入S信号组成。$O$被认为是与S,E相互作用服从薛定谔方程(SE)的量子物体。MS不完全或限制状态的$O$推导的代数QM形式主义,利用西格尔和$C^*$ -代数。从系统子代数的Segal定理出发,证明了这种限制状态$V^O=|O_j> < O_j|$描述了$O$在单个事件中观察到的经典随机“指针”结果$O_j$.由$O$定义的“优选”基础$|O_j>$通过$O$ - E相互作用状态去相干。

英文摘要:

Quantum Measurement problem studied in Information Theory approach of systems selfdescription which exploits the information acquisition incompleteness for the arbitrary information system. The studied model of measuring system (MS) consist of measured state S environment E and observer $O$ processing input S signal. $O$ considered as the quantum object which interaction with S,E obeys to Schrodinger equation (SE). MS incomplete or restricted states for $O$ derived by the algebraic QM formalism which exploits Segal and $C^*$-algebras. From Segal theorem for systems subalgebras it's shown that such restricted states $V^O=|O_j> < O_j|$ describes the classical random 'pointer' outcomes $O_j$ observed by $O$ in the individual events. The 'preferred' basis $|O_j>$ defined by $O$ state decoherence via $O$ - E interactions.
