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

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

Identifying the spatiotemporal characteristics and obstacle factors of the agricultural drought
disaster risk is essential to reduce grain losses and ensure food security. However, due to …

The uncertainty relation is a distinguishing feature of quantum theory, characterizing the
incompatibility of noncommuting observables in the preparation of quantum states. Recently …

It is well known that the violation of a local uncertainty relation can be used as an indicator
for the presence of entanglement. Unfortunately, the practical use of these nonlinear …

The uncertainty relation, as one of the fundamental principles of quantum physics, captures
the incompatibility of noncommuting observables in the preparation of quantum states. In …

For a pair of observables, they are called “incompatible” if and only if their commutator does
not vanish, which represents one of the key features in quantum mechanics. The question is …

Nonlocality, which is the key feature of quantum theory, has been linked with the uncertainty
principle by fine-grained uncertainty relations, by considering combinations of outcomes for …

EPR steering is an asymmetric quantum correlation, as such, it is an important resource for
quantum information protocols, like those used in quantum key distribution that are of …

We consider the uncertainty between two pairs of local projective measurements performed
on a multipartite system. We show that the optimal bound in any linear uncertainty relation …
