  We study the dissipative dynamics of interferometric power as a discordlike
measure in Markovian environments, such as dephasing, depolarizing, and
generalized amplitude damping. Moreover, we compare the dynamics of
interferometric power and entanglement by choosing proper initial conditions.
Our study shows that in all cases where the sudden death of entanglement
appears, interferometric power decays asymptotically. Therefore, quantum
metrology based on interferometric power is more robust than entanglement.
