    "abstract": "We directly sample the exponential moments of the canonical phase for various\nquantum states from the homodyne output. The method enables us to study the\nphase properties experimentally, without making the detour via reconstructing\nthe density matrix or the Wigner function and calculating the phase statistics\nfrom them. In particular, combing the measurement with a measurement of the\nphoton-number variance, we verify fundamental number-phase uncertainty.",
