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 …

Quantum resource theories (QRTs) offer a highly versatile and powerful framework for
studying different phenomena in quantum physics. From quantum entanglement to quantum …

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 …

We investigate the relation between the incompatibility of quantum measurements and
quantum nonlocality. We show that a set of measurements is not jointly measurable (ie …

In 1960, the mathematician Ernst Specker described a simple example of nonclassical
correlations, the counter-intuitive features of which he dramatized using a parable about a …

It is well known that jointly measurable observables cannot lead to a violation of any Bell
inequality—independent of the state and the measurements chosen at the other site. In this …

In quantum mechanics performing a measurement is an invasive process which generally
disturbs the system. Due to this phenomenon, there exist incompatible quantum …

Measurement incompatibility describes two or more quantum measurements whose
expected joint outcome on a given system cannot be defined. This purely nonclassical …

While there is general consensus on the definition of incompatible POVMs, moving up to the
level of instruments one finds a much less clear situation, with mathematically different and …

The notorious Wigner's friend thought experiment (and modifications thereof) has received
renewed interest especially due to new arguments that force us to question some of the …
