Query: Generalized Weyl quantization on the cylinder and quantum phase   Generalized Weyl quantization formalism for the cylindrical phase space $S^1
\times \mathbb{R}^1$ is developed. It is shown that the quantum observables
relevant to the phase of linear harmonic oscillator or electromagnetic field
can be represented within this formalism by the self-adjoint operators on the
Hilbert space $L^2(S^1)$.
