Number-phase uncertainty relations: Verification by balanced homodyne measurement
Tomáš Opatrný, Mohammed Dakna, D.‐G. Welsch · Physical Review A · 1998
It is shown that fundamental uncertainty relations between photon number and canonical phase of a single-mode optical field can be verified by means of a balanced homodyne measurement. All the relevant quantities can be sampled directly from the measured phase-dependent quadrature distribution.
