    "abstract": "In this paper we address the problem of optimal reconstruction of a quantum\nstate from the result of a single measurement when the original quantum state\nis known to be a member of some specified set. A suitable figure of merit for\nthis process is the fidelity, which is the probability that the state we\nconstruct on the basis of the measurement result is found by a subsequent test\nto match the original state. We consider the maximisation of the fidelity for a\nset of three mirror symmetric qubit states. In contrast to previous examples,\nwe find that the strategy which minimises the probability of erroneously\nidentifying the state does not generally maximise the fidelity.",
