TABLE II. Theoretical values. The table reports the theoretical values of the SLDF, which is the smallest quantum Fisher information (multiplying it by a constant turns it into the biggest one; see Sec. V), the lower bound Sτ (ρp,H2) [Eq. (4)], and the related entanglement witness conditions [Eq. (5)], for the Bell state mixture ρp and the spin Hamiltonians H2.
