    "abstract": "We present the first experimental demonstration of the maximum confidence\nmeasurement strategy for quantum state discrimination. Applying this strategy\nto an arbitrary set of states assigns to each input state a measurement outcome\nwhich, when realized, gives the highest possible confidence that the state was\nindeed present. The theoretically optimal measurement for discriminating\nbetween three equiprobable symmetric qubit states is implemented in a\npolarization-based free-space interferometer. The maximum confidence in the\nmeasurement result is 2/3. This is the first explicit demonstration that an\nimprovement in the confidence over the optimal minimum error measurement is\npossible for linearly dependent states.",
