Yin et. al. used the Micius satellite for a record demonstration of this phenomenon in collaboration with the Chinese QUESS initiative. Artur Ekert developed the E91 protocol which contrasts with the BB84 protocol in the explicit use of this phenomenon. (15[1]-5[1])This phenomenon can occur when a laser beam directed at a BBO crystal (-5[1])experiences spontaneous (-5[1])parametric down conversion. The CHSH (15[1])inequality (15[1])is used to evaluate (*) experimental confirmation of this phenomenon. (10[2])The presence of this phenomenon differentiates Young’s double slit experiment from the quantum eraser experiment and can’t be explained by local hidden variables according to Bell’s theorem. For 10 points, name this phenomenon where the quantum states of particles (10[1])can’t be described separately leading to (10[1])“spooky action at a distance.” ■END■ (10[1])
