Transformation from Arep to Brep: Suppose there is another hermitian operator B op . > >= n n n op b b b B   , where n = 1, 2, . .., n max . We can expand the ket  ψ > in terms of the eigenkets of B op ( the Brepresentation ) we get ∑ = > >= max 1   n n n b b n with 1   max 1 = >< ∑ = n n n n b b .
