Query: Entropic entanglement criteria in phase space   We derive entropic inseparability criteria for the phase space representation
of quantum states. In contrast to criteria involving differential entropies of
marginal phase space distributions, our criteria are based on a joint
distribution known as the Husimi Q-distribution. This distribution is
experimentally accessible in cold atoms, circuit QED architectures and photonic
systems and bears practical advantages compared to the detection of marginals.
We exemplify the strengths of our entropic approach by considering several
classes of non-Gaussian states where second-order criteria fail. We show that
our criteria certify entanglement in previously undetectable regions
highlighting the strength of using the Husimi Q-distribution for entanglement
detection.
