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

A central result in the foundations of quantum mechanics is the Kochen-Specker theorem. In
short, it states that quantum mechanics is in conflict with classical models in which the result …

Some measurements in quantum mechanics disturb each other. This has puzzled physicists
since the formulation of the theory, but only in recent decades has the incompatibility of …

In the context of a physical theory, two devices, A and B, described by the theory are called
incompatible if the theory does not allow the existence of a third device C that would have …

The fact that not all measurements can be carried out simultaneously is a peculiar feature of
quantum mechanics and is responsible for many key phenomena in the theory, such as …

Quantum steering refers to the possibility for Alice to remotely steer Bob's state by
performing local measurements on her half of a bipartite system. Two necessary ingredients …

Resource theories can be used to formalize the quantification and manipulation of resources
in quantum information processing such as entanglement, asymmetry and coherence of …

Whether positive operator-valued measures (POVMs) provide advantages in demonstrating
Bell nonlocality has remained unknown, even in the simple scenario of Einstein-Podolsky …

Estimation of expectation values of incompatible observables is an essential practical task in
quantum computing, especially for approximating energies of chemical and other many …

Quantum mechanics challenges our intuition on the cause-effect relations in nature. Some
fundamental concepts, including Reichenbach's common cause principle or the notion of …
