- Abstract: Empirical falsifiability of the predictions of physical theories is the
cornerstone of the scientific method. Physical theories attribute empirically
falsifiable operational properties to sets of physical preparations. A theory
is said to be empirically complete if such properties allow for a not
fine-tuned realist explanation, as properties of underlying probability
distributions over states of reality. Such theories satisfy a family of
equalities among fundamental operational properties, characterized exclusively
by the number of preparations. Quantum preparations deviate from these
equalities, and the maximal quantum deviation increases with the number of
preparations. These deviations not only signify the incompleteness of the
operational quantum formalism, but they simultaneously imply quantum over
classical advantage in suitably constrained one-way communication tasks,
highlighting the delicate interplay between the two.

Two particles are identical if all their intrinsic properties, such as spin and charge, are the same.
Quantum mechanics is seen as a normative and algorithmic theory guiding an agent to assess her subjective beliefs represented as (coherent) sets of gambles.
We show how sets of exchangeable observables (gambles) may be updated after a measurement and discuss the issue of defining entanglement for indistinguishable particle systems.

We aim to shed some light on the quantum-to-classical transition as seen through the analysis of uncertainty relations.
We employ entropic uncertainty relations to show that it is only by the inclusion of imprecision in our model of macroscopic measurements that we can prepare a system with two simultaneously well-defined quantities.

Bell's experiment description assumes the (Quantum Mechanics-language equivalent of the classical) condition of Locality.
This result is complementary to a recently published one demonstrating that non-Locality is necessary to describe said experiment.
It is concluded that, within the framework of Quantum Mechanics, there is absolutely no reason to believe in the existence of non-Local effects.
