Spintronics and quantum information science are two promising candidates for innovating
information processing technologies. The combination of these two fields enables us to build …

Quantum correlations between two parties are essential for the argument of Einstein,
Podolsky, and Rosen in favor of the incompleteness of quantum mechanics. Schrödinger …

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 …

We develop the concept of genuine N-partite Einstein-Podolsky-Rosen (EPR) steering. This
nonlocality is the natural multipartite extension of the original EPR paradox. Useful …

Monogamy inequalities for the way bipartite Einstein-Podolsky-Rosen (EPR) steering can be
distributed among N systems are derived. One set of inequalities is based on witnesses with …

Einstein-Podolsky-Rosen (EPR) steering is a type of characteristic nonlocal correlation and
provides an important resource in quantum information tasks, especially in view of its …

We demonstrate that the many-body nonlocality witnessed by a broad family of Bell
inequalities is a resource for ultraprecise metrology. We formulate a general scheme which …

We demonstrate that the one-axis twisting (OAT), a versatile method of creating nonclassical
states of bosonic qubits, is a powerful source of many-body Bell correlations. We develop a …

Einstein-Podolsky-Rosen (EPR) steering, a category of quantum nonlocal correlations
describing the ability of one observer to influence another party's state via local …

Quantum steering is the phenomenon whereby one party (Alice) proves entanglement by
“steering” the system of another party (Bob) into distinct ensembles of states, by performing …
