Entropic entanglement now on the arXiv!

Our new paper, Entropic entanglement criteria in phase space, has recently appeared on the arXiv! It is well known that entanglement is incredibly hard not just to measure, but also to witness.

Entropic entanglement criteria in phase space

We derive inseparability criteria for the phase space representation of quantum states in terms of variants of Wehrl's entropy. In contrast to entropic criteria involving differential entropies of marginal phase space distributions, our criteria are …
