We introduce the framework of general probabilistic theories (GPTs for short). GPTs are a
class of operational theories that generalize both finite-dimensional classical and 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 …

The notion of uncertainty in the description of a physical system has assumed prodigious
importance in the development of quantum theory. Overcoming the early misunderstanding …

We prove that given any two general probabilistic theories (GPTs) the following are
equivalent:(i) each theory is nonclassical, meaning that neither of their state spaces is a …

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

We investigate the possibility of multiple uses of a single copy of a three-qubit state for
detecting genuine tripartite Einstein-Podolsky-Rosen (EPR) steering. A pure three-qubit …

We explore the possibility of multiple usage of a single genuine entangled state by
considering a scenario consisting of three spin-1 2 particles shared between Alice, Bob, and …

Is entanglement an exclusive feature of quantum systems, or is it common to all non-
classical theories? And if this is the case, how strong is quantum mechanical entanglement …

The existence of incompatible observables is a cornerstone of quantum mechanics and a
valuable resource in quantum technologies. Here we introduce a measure of incompatibility …

The existence of incompatible measurements is a fundamental phenomenon having no
explanation in classical physics. Intuitively, one considers given measurements to be …
