摘要：

An entangled pair of photons (1 and 2) are emitted in opposite directions. A narrow slit is placed in the path of photon 1 to provide the precise knowledge of its position on the y-asis 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, that is, a greater Delta p(y) because of the precise knowledge of its position y? The experimental data show Delta y Delta p(y) < h for photon 2. Can this recent realization of the thought experiment of Karl Popper signal at violation of the uncertainty principle?
