    "abstract": "We discuss an interferometric approach to the estimation of quantum\nmechanical damping. We study specific classes of entangled and separable probe\nstates consisting of superpositions of coherent states. Based on the assumption\nof limited quantum resources we show that entanglement improves the estimation\nof an unknown damping constant.",
