According to the fundamental idea that a steering inequality can be constructed by just considering the measurements performed by Bob, and from the definitions of steering from Alice to Bob, a general scheme for designing linear steering inequalities (LSIs) is developed to detect the genuine multipartite two-way steerability. A special class of LSIs, which are constructed from the Bell operators, are introduced. Furthermore, several other types of LSIs are also considered.
Within the hierarchy of inseparable quantum correlations, Einstein-Podolsky-Rosen steering is distinguished from both entanglement and Bell nonlocality by its asymmetry -- there exist conditions where the steering phenomenon changes from being observ
The existence of non-local quantum correlations is certainly the most important specific property of the quantum world. However, it is a challenging task to distinguish correlations of classical origin from genuine quantum correlations, especially wh
The standard definition of genuine multipartite entanglement stems from the need to assess the quantum control over an ever-growing number of quantum systems. We argue that this notion is easy to hack: in fact, a source capable of distributing bipart
The quantum entanglement as one of very important resources has been widely used in quantum information processing. In this work, we present a new kind of genuine multipartite entanglement. It is derived from special geometric feature of entangled sy
Quantifying genuine entanglement is a crucial task in quantum information theory. In this work, we give an approach of constituting genuine $m$-partite entanglement measure from any bipartite entanglement and any $k$-partite entanglement measure, $3l
