抄録

The measurement scenario of unambiguous quantum-state filtering where one particular signal is unambiguously extracted from a set of non-orthogonal signals is discussed. The maximum detection probability and its corresponding measurement operators are given by simple expressions although the formalism includes mixed state signals. As an application, the sensing of decoherence in quantum channels is considered.
