DOI: 10.1007/s11128-020-02721-6
Abstract: We investigate bipartite entanglement and quantum steering in a three-mode, hybrid electro-optomechanical system consisting of a Fabry–Perot optical cavity, a nanomechanical oscillator and a lumped-element microwave cavity. The nanomechanical resonator is directly coupled to the… read more here.

DOI: 10.1016/j.rinp.2021.104636
Abstract: Abstract Asymmetric quantum steering can achieve one-way control, which is different from multipartite quantum steering and can accomplish some work that quantum entanglement cannot complete. The cascaded nonlinear process of spontaneous parametric down-conversion cascaded with… read more here.

DOI: 10.1088/1674-1056/ac401f
Abstract: Realistic quantum systems always exhibit gravitational and relativistic features. In this paper, we investigate the properties of Gaussian steering and its asymmetry by the localized two-mode Gaussian quantum states, instead of the traditional single-mode approximation… read more here.

DOI: 10.1088/1751-8121/aad115
Abstract: We address the problem of quantum nonlocality with positive operator valued measures (POVM) in the context of Einstein-Podolsky-Rosen quantum steering. We show that, given a candidate for local hidden state (LHS) ensemble, the problem of… read more here.

DOI: 10.1103/physrevlett.122.070402
Abstract: The set of all qubit states that can be steered to by measurements on a correlated qubit is predicted to form an ellipsoid-called the quantum steering ellipsoid-in the Bloch ball. This ellipsoid provides a simple… read more here.

DOI: 10.1103/physrevlett.124.120402
Abstract: We show-both theoretically and experimentally-that Einstein-Podolsky-Rosen steering can be distilled. We present a distillation protocol that outputs a perfectly correlated system-the singlet assemblage-in the asymptotic infinite-copy limit, even for inputs that are arbitrarily close to… read more here.

DOI: 10.1364/oe.486398
Abstract: Noise-adding methods have been widely used to manipulate the direction of quantum steering, but all related experimental schemes only worked under the assumption that Gaussian measurements were performed and ideal target states were accurately prepared.… read more here.
