A proof for the informational completeness of the rotated quadrature observables

J. Kiukas, P. Lahti, J. -P. Pellonpaa

We give a new mathematically rigorous proof for the fact that, when $S$ is a dense subset of $[0,2\pi )$, the rotated quadrature operators $Q_{\theta }$, $\theta \in S$, of a single mode electromag…
