the experiment consists of this entangled state being shared between two experimenters, each of whom has the ability to measure either with respect to the basis formula_53 or formula_54. we see that if they each measure with respect to formula_53, then they never see the outcome formula_56. if one measures with respect to formula_53 and the other formula_54, they never see the outcomes formula_59 formula_60 however, sometimes they see the outcome formula_61 when measuring with respect to formula_54, since formula_63
