A. P. Alodjants, A. Yu. Leksin, S. M. Arakelian

摘要:

本文考虑在希尔伯特空间中用SU(3)对称性偏振映射描述具有Gell-Mann内部对称性的量子光学玻色系统。首次讨论了三模光场密度(或相干性)矩阵元的实用测量。我们引入了一组算符来描述三能级系统的振幅和相位特性的量子测量过程和涨落行为。提出了一种用于并行测量盖尔曼参数的十二端口干涉仪。研究了在该测量方法下W-qutrit态的量子特性。

英文摘要:

We consider a new approach to describe a quantum optical Bose-system with internal Gell-Mann symmetry by the SU(3)-symmetry polarization map in Hilbert space. The operational measurement in density (or coherency) matrix elements for the three mode optical field is discussed for the first time. We have introduced a set of operators that describes the quantum measurement procedure and the behavior of fluctuations for the amplitude and phase characteristics of three level system. The original twelve-port interferometer for parallel measurements of the Gell-Mann parameters is proposed. The quantum properties of W-qutrit states under the measurement procedure are examined.
