基于熵权的单参数不确定关系类

One-parameter class of uncertainty relations based on entropy power

Petr Jizba, Yue Ma, Anthony Hayes, Jacob A. Dunningham

摘要:

我们使用熵功率的概念,推导出一个新的单参数类的信息理论的不确定性关系的共轭观测对在无限维希尔伯特空间。这一类构成了高阶统计不确定性关系的无限塔,原则上允许通过测量相关的熵功率来确定潜在信息分布函数的形状。我们通过讨论两个例子说明了新类的能力:真空和压缩态的叠加和柯西型重尾波函数。

英文摘要:

We use the concept of entropy power to derive a new one-parameter class of information-theoretic uncertainty relations for pairs of conjugate observables in an infinite-dimensional Hilbert space. This class constitutes an infinite tower of higher-order statistics uncertainty relations, which allows one in principle to determine the shape of the underlying information-distribution function by measuring the relevant entropy powers. We illustrate the capability of the new class by discussing two examples: superpositions of vacuum and squeezed states and the Cauchy-type heavy-tailed wave function.
