A proof for the informational completeness of the rotated quadrature observables


الملخص بالإنكليزية

We give a new mathematically rigorous proof for the fact that, when $S$ is a dense subset of $[0,2pi)$, the rotated quadrature operators $Q_theta$, $thetain S$, of a single mode electromagnetic field constitute an informationally complete set of observables.
