  1. The first column corresponds to Anita’s Bell measurements, and the first row lists the possible measurement outcomes for Babai who has an OTC assisted computer. Anita and Babai share the Bell state that is listed in the cell in row and column corresponding to their measurement outcomes. Here γ = (α2 − β2)2 and δ = (2αβ)2.
