    "abstract": "We discuss the possibility of sampling exponential moments of the canonical\nphase from the s-parametrized phase space functions. We show that the sampling\nkernels exist and are well-behaved for any s\u003e-1, whereas for s=-1 the kernels\ndiverge in the origin. In spite of that we show that the phase space moments\ncan be sampled with any predefined accuracy from the Q-function measured in the\ndouble-homodyne scheme with perfect detectors. We discuss the effect of\nimperfect detection and address sampling schemes using other measurable\nphase-space functions. Finally, we discuss the problem of sampling the\ncanonical phase distribution itself.",
