Query: Measuring Gaussian quantum information and correlations using the Renyi
  entropy of order 2   We demonstrate that the Renyi-2 entropy provides a natural measure of
information for any multimode Gaussian state of quantum harmonic systems,
operationally linked to the phase-space Shannon sampling entropy of the Wigner
distribution of the state. We prove that, in the Gaussian scenario, such an
entropy satisfies the strong subadditivity inequality, a key requirement for
quantum information theory. This allows us to define and analyze measures of
Gaussian entanglement and more general quantum correlations based on such an
entropy, which are shown to satisfy relevant properties such as monogamy.
