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 …

Entropic entanglement now published in PRA

Our new paper, Entropic entanglement criteria in phase space, has recently been published in Physical Review A! It is well known that entanglement is incredibly hard not just to measure, but also to witness.
