    "abstract": "In this paper, we consider the generalized measurement where one particular\nquantum signal is unambiguously extracted from a set of non-commutative quantum\nsignals and the other signals are filtered out. Simple expressions for the\nmaximum detection probability and its POVM are derived. We applyl such\nunambiguous quantum state filtering to evaluation of the sensing of decoherence\nchannels. The bounds of the precision limit for a given quantum state of probes\nand possible device implementations are discussed.",
