Abstract
We directly sample the exponential momenta of the canonical phase for various quantum states from the homodyne output. The method enables us to study the phase properties experimentally, without making the deto ur via reconstructing the density matrix or the Wigner function and ca lculating the phase statistics from them. In particular, combing the m easurement with a measurement of the photon-number variance, we verify fundamental number-phase uncertainty. (C) 1998 Elsevier Science B.V. All rights reserved.
