经典系统与量子系统之间的距离

The Distance Between Classical and Quantum Systems

Deanna Abernethy, John R. Klauder

摘要:

在最近的一篇论文中,定义了一个“距离”函数,\cal D,它测量了纯经典系统和量子系统之间的距离。在这项工作中,我们提出了一个新的定义的“距离”,D,它衡量的距离,无论是纯或不纯的经典和量子态。我们还比较了新的距离公式与以前的公式,当后者适用。为了说明这些距离,为了简单和清晰起见,我们使用了2个\times 2矩阵示例和2维向量。计算了几个具体的例子。

英文摘要:

In a recent paper, a "distance" function, \cal D, was defined which measures the distance between pure classical and quantum systems. In this work, we present a new definition of a "distance", D, which measures the distance between either pure or impure classical and quantum states. We also compare the new distance formula with the previous formula, when the latter is applicable. To illustrate these distances, we have used 2 \times 2 matrix examples and 2-dimensional vectors for simplicity and clarity. Several specific examples are calculated.
