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