    "abstract": "We investigate an imbalance between the sensitivity of the common state\nmeasures--fidelity, trace distance, concurrence, tangle, von Neumann entropy\nand linear entropy--when acted on by a depolarizing channel. Further, in this\ncontext we explore two classes of two-qubit entangled mixed states.\nSpecifically, we illustrate a sensitivity imbalance between three of these\nmeasures for depolarized (i.e., Werner-state like) nonmaximally entangled and\nmaximally entangled mixed states, noting that the size of the imbalance depends\non the state\u0027s tangle and linear entropy.",
