    "abstract": "The theory of generalised measurements is used to examine the problem of\ndiscriminating unambiguously between non-orthogonal pure quantum states.\nMeasurements of this type never give erroneous results, although, in general,\nthere will be a non-zero probability of a result being inconclusive. It is\nshown that only linearly-independent states can be unambiguously discriminated.\nIn addition to examining the general properties of such measurements, we\ndiscuss their application to entanglement concentration.",
