量子测不准的几何推导

Geometric derivation of quantum uncertainty

Alexey A. Kryukov

摘要:

量子可观测量可以用归一化态球上的矢量场来识别。因此,量子可观测量的不确定关系变成了几何陈述。在信中熟悉的不确定性关系如下从以下更强的声明:所有平行四边形与给定的双方的矩形具有最大的面积。

英文摘要:

Quantum observables can be identified with vector fields on the sphere of normalized states. Consequently, the uncertainty relations for quantum observables become geometric statements. In the Letter the familiar uncertainty relation follows from the following stronger statement: Of all parallelograms with given sides the rectangle has the largest area.
