Nonlocality is the most characteristic feature of quantum mechanics, but recent research
seems to suggest the possible existence of nonlocal correlations stronger than those …

The framework of generalized probabilistic theories is a powerful tool for studying the
foundations of quantum physics. It provides the basis for a variety of recent findings that …

It is a relatively new insight of classical statistics that empirical data can contain information
about causation rather than mere correlation. First algorithms have been proposed that are …

We reconstruct the explicit formalism of qubit quantum theory from elementary rules on an
observer's information acquisition. Our approach is purely operational: we consider an …

Abstract In QBism (or quantum Bayesianism) a quantum state does not represent an
element of physical reality but an agentʼs personal probability assignments, reflecting his …

Does information play a significant role in the foundations of physics? Information is the
abstraction that allows us to refer to the states of systems when we choose to ignore the …

These lecture notes provide a basic introduction to the framework of generalized
probabilistic theories (GPTs) and a sketch of a reconstruction of quantum theory (QT) from …

We develop an operational approach for reconstructing the quantum theory of qubit systems
from elementary rules on information acquisition. The focus lies on an observer $ O …

Abstract In Xin et al (2017 Phys. Rev. A 96 062303) and Wei et al (2018 Sci. China Phys.
Mech. Astron. 61 70311), the authors reported an algorithm to simulate, in a circuit-based …

Where does quantum mechanics part ways with classical mechanics? How does quantum
randomness differ fundamentally from classical randomness? We cannot fully explain how …
