    "abstract": "We present, and analyze thoroughly, a highly symmetric and efficient scheme\nfor the determination of a single-qubit state, such as the polarization\nproperties of photons emitted by a single-photon source. In our scheme there\nare only four measured probabilities, just enough for the determination of the\nthree parameters that specify the qubit state, whereas the standard procedure\nwould measure six probabilities.",
