Magnon-photon coupling inside a cavity has been experimentally realized and has attracted
significant attention for its potential docking with quantum information science. Whether this …

Abstract Entanglement and Einstein–Podolsky–Rosen (EPR) steering are nonlocal quantum
correlations, which are relevant resources for quantum information protocols. EPR steering …

Quantum steering describes a phenomenon whereby one system can immediately influence
another via local measurements. It can be detected by violating the powerful and useful …

Einstein-Podolsky-Rosen (EPR) steering has potential applications in quantum information
processing. Here the genuine tripartite EPR steering is investigated in cascaded nonlinear …

Abstract Einstein–Podolsky–Rosen (EPR) steering is the key resources in quantum
information processing. EPR steering light sources typically obtained through spontaneous …

Abstract Einstein–Podolsky–Rosen (EPR) steering is an example of nontrivial quantum
nonlocality and characteristic in the non-classical world. The directivity (or asymmetry) is a …

Importance of quantum entanglement has been demonstrated in various applications.
Usually, separability of a bipartite state is defined by its algebraic structure, ie a convex …

We study Einstein-Podolsky-Rosen (EPR) steering properties of quantum phases in the
generalized Dicke model (GDM) generated by a cavity Bose-Einstein condensate (BEC) …

Bell nonlocality of quantum states is an important resource in quantum information and then
has various applications. It is usually detected by the violation of some Bell's inequalities …

Motivated by the contributions [Sci. Rep. 6, 39063 (2016)] and [Phys. Rev. A 98, 052114
(2018)], we aim to establish a new method for theoretically checking Bell nonlocality of a …
