基于广义斜信息的不确定性与互补关系

Uncertainty and complementarity relations based on generalized skew information

Huaijing Huang, Zhaoqi Wu, Shao-Ming Fei

摘要:

测不准关系和互补关系是量子力学和量子信息理论的核心问题。利用广义Wigner-Yanase-Dyson(GWYD)斜信息,分别推导了关于互无偏测量(MUM)和一般对称信息完备正算子值测量(SIC-POVM)的不确定性和互补关系.我们的结果包括一些现有的特殊情况。我们还通过提供一个详细的例子来验证我们的结果。

英文摘要:

Uncertainty relations and complementarity relations are core issues in quantum mechanics and quantum information theory. By use of the generalized Wigner-Yanase-Dyson (GWYD) skew information, we derive several uncertainty and complementarity relations with respect to mutually unbiased measurements (MUMs), and general symmetric informationally complete positive operator valued measurements (SIC-POVMs), respectively. Our results include some existing ones as particular cases. We also exemplify our results by providing a detailed example.
