... Intuition: If Range(f) and Range(g) are disjoint, then the H register decoheres all entanglement between R and B, leaving only classical correlation If, on the other hand, Range(f)=Range(g), then there’s some permutation of the |x,1R states that puts the last qubit of R into an EPR pair with B Thus ...
