Yin et. al. used the Micius satellite for a record demonstration of this phenomenon in collaboration with the Chinese (15[1])QUESS initiative. Artur Ekert developed the E91 protocol which contrasts with the BB84 protocol (15[1])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 (15[1])down conversion. (-5[1])The CHSH (15[1]-5[1])inequality (15[1])is used to evaluate (*) experimental confirmation of this (10[1])phenomenon. (10[3]-5[1])The presence (10[1])of this phenomenon differentiates Young’s double slit experiment from the quantum eraser (-5[1])experiment and can’t be explained (-5[1])by local (10[1]-5[1])hidden variables (10[1])according to (10[2])Bell’s (10[3])theorem. (10[1]-5[1])For 10 points, (10[1])name this (10[2])phenomenon (10[1])where the quantum states of particles (10[1])can’t be (10[1])described (-5[1])separately (10[1])leading to (10[2])“spooky action at a distance.” (10[1])■END■ (10[8])
