量子力学中的干涉与可区分性

量子物理 2007-05-23 v1

摘要

我们引入定量度量来刻画给定测量中两个量子态的不可区分性 UU 以及该测量中可观测的干涉量 II。表明这些度量满足不等式 UIU\geq I,该式可视为对玻尔论断的精确表述:人们不能在保持干涉现象的同时区分粒子的两条可能路径。此表述被应用于 Badurek 等人的中子干涉仪实验。表明该表述比这些作者所考虑的基于相位与光子数不确定关系的论证更强。

In view of the recent debates in Nature and New Scientist on the question whether Heisenberg's uncertainty relations are strong enough to explain complementarity in a double-slit experiment, we have decided to make this 11 year old paper available as e-print. A few misprints have been corrected and 2 footnotes added
