Quantum steering refers to the non-classical correlations that can be observed between the
outcomes of measurements applied on half of an entangled state and the resulting post …

Is entanglement an exclusive feature of quantum systems, or is it common to all non-
classical theories? And if this is the case, how strong is quantum mechanical entanglement …

We investigate the resources needed for secure teleportation of coherent states. We extend
continuous variable teleportation to include quantum teleamplification protocols that allow …

Einstein-Rosen-Podolsky (EPR) steering or quantum steering describes the “spooky action
at a distance” that one party is able to remotely alter the states of the other if they share a …

Einstein-Podolsky-Rosen steering is a form of inseparability in quantum theory commonly
acknowledged to be intermediate between entanglement and Bell nonlocality. However, this …

We derive laws for the distribution of quantum steering among different parties in multipartite
Gaussian states under Gaussian measurements. We prove that a monogamy relation akin to …

In this paper, we investigated the quantum correlation of nano-electro-optomechanical
system enhanced by an optical parametric amplifier (OPA) and Coulomb-type interaction. In …

Einstein-Podolsky-Rosen steering is a manifestation of quantum correlations exhibited by
quantum systems that allows for entanglement certification when one of the subsystems is …

The certification of Bell nonlocality or quantum steering implies the use of incompatible
measurements. Here we make this connection quantitative. We show how to strengthen …

We derive fundamental constraints for the Schur complement of positive matrices, which
provide an operator strengthening to recently established information inequalities for …
