标题： Popper's test of quantum mechanics and two-photon "ghost" diffraction

摘要： 一个很久以前由卡尔·波普尔提出的量子力学测试被重新考虑，并提供了更详细的分析和新的见解。 在该提议中存在一个模糊之处，后来发现这一模糊之处对于使测试具有决定性至关重要，这是首次识别并加以考虑。 其对最近进行的光子实验[例如D. V. Strekalov \textit{等.}，Phys. Rev. Lett. {\bf 74}，3600 (1995)] 的影响进行了简要分析。 显示英文摘要

摘要： A test on quantum mechanics proposed long ago by Karl Popper is reconsidered with further detail and new insight. An ambiguity in the proposal, which turns out to be essential in order to make the test conclusive, is identified and taken into account for the first time. Its implications for recently performed photon experiments [such as in D. V. Strekalov \textit{et al.}, Phys. Rev.\ Lett. {\bf 74}, 3600 (1995)] are briefly analyzed.
