    • These solutions are minimizing the overlap. Stationarity equations do not differ maximums and mimimums and give both extremes. Surprisingly, there is a solution which, depending on state parameters, maximizes the overlap for some states and minimizes for some other states. This solution is presented in Sec..

    • Notice that when t=0, the phase γ can be further made zero by changing local phases as eiγ can be absorbed in the definition of the product state | 111. It turns out that for 0≤γ≤π/4, the maximal entanglement is achieved when t=0 and GHZ is the only maximally entangled state in this range.
