dc.description.abstractAn 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-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, that is, a greater Δp* because of the precise knowledge of its position y? The experimental data show Δy Δ p* < h for photon 2. Can this recent realization of the thought experiment of Karl Popper signal a violation of the uncertainty principle? *= subscript y
