Query: A Classical Bound on Quantum Entropy   A classical upper bound for quantum entropy is identified and illustrated,
$0\leq S_q \leq \ln (e \sigma^2 / 2\hbar)$, involving the variance $\sigma^2$
in phase space of the classical limit distribution of a given system. A
fortiori, this further bounds the corresponding information-theoretical
generalizations of the quantum entropy proposed by Renyi.
