波普尔实验的实验实现:违反了不确定原理?

Experimental realization of Popper's Experiment: Violation of the Uncertainty Principle?

Yoon-Ho Kim, Yanhua Shih

摘要:

一对纠缠的光子(1和2)被发射到相反的方向。在光子1的路径中放置一个窄缝,以提供其在$y$轴上的位置的精确知识,并且由于量子纠缠,这也确定了其孪生光子2的精确$y$位置。光子2的动量是否会有更大的不确定性,一个更大的$Δp_{y}$,由于其位置的精确知识$y$?实验数据显示光子2的$ΔyΔp_{y}<\hbar $。卡尔·波普尔(Karl Popper)的历史思想实验最近的实现是否标志着对不确定原理的违反?

英文摘要:

An entangled pair of photons (1 and 2) are emitted to opposite directions. A narrow slit is placed in the path of photon 1 to provide precise knowledge of its position on the $y$ axis and this also determines the precise $y$ position of its twin, photon 2, due to quantum entanglement. Is photon 2 going to experience a greater uncertainty in momentum, i.e., a greater $Δp_{y}$, due to the precise knowledge of its position $y$? The experimental data shows $ΔyΔp_{y}<\hbar $ for photon 2. Can this recent realization of the historical thought experiment of Karl Popper signal a violation of the uncertainty principle?
