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 …

We establish an operational characterization of general convex resource theories—
describing the resource content of not only states but also measurements and channels …

We report an alternative scheme for implementing generalized quantum measurements that
does not require the usage of an auxiliary system. Our method utilizes solely (a) classical …

In quantum theory, the no-information-without-disturbance and no-free-information theorems
express that those observables that do not disturb the measurement of another observable …

We introduce the post-processing preorder and equivalence relations for general
measurements on a possibly infinite-dimensional general probabilistic theory described by …

Random access codes (RACs) are an intriguing class of communication tasks that reveal an
operational and quantitative difference between classical and quantum information …

Studying sequential measurements is of the utmost importance to both the foundational
aspects of quantum theory and the practical implementations of quantum technologies, with …

The formalism of general probabilistic theories provides a universal paradigm that is suitable
for describing various physical systems including classical and quantum ones as particular …

We investigate the question which communication tasks can be accomplished within a given
operational theory. The concrete task is to find out which communication matrices have a …

We develop a method for semi-device-independent certification of the number of
measurements. We achieve this by testing whether Bob's steering equivalent observables …
