Any temperature-dependent unitary driving on a thermalized quantum probe universally boosts its quantum Fisher information for thermometry above the static equilibrium value via a positive kernel of information currents.
Thus, the initial manifold is that of Gibbs states{π0(β)}, equipped with QFIF β π0 = Varπ0(H0)
