Query: On a Stroboscopic Approach to Quantum Tomography of Qudits Governed by
  Gaussian Semigroups   In this paper, we discuss the minimal number of observables, where
expectation values at some time instant determine the trajectory of a d-level
quantum system ("qudit") governed by the Gaussian semigroup. We assume that the
macroscopic information about the system in question is given by the mean
values of n selfadjoint operators $Q_1,...,Q_n$ at some time instants
$t_1<t_2<...<t_r$, where $n<d^2-1$ and $r\leq {\rm deg} \mu(\lambda,\bBBL)$.
Here $\mu(\lambda,\bBBL)$ stands for the minimal polynomial of the generator of
the Gaussian flow.
