Interference phenomena are often claimed to resist classical explanation. However, such
claims are undermined by the fact that the specific aspects of the phenomenology upon …

Quantum interference phenomena are widely viewed as posing a challenge to the classical
worldview. Feynman even went so far as to proclaim that they are the $\textit {only mystery} …

In this paper we relate notions of nonclassicality in what is known as the simplest nontrivial
scenario (a prepare and measure scenario composed of four preparations and two binary …

In this work we focus on two classes of games: xor nonlocal games and xor* sequential
games with monopartite resources. xor games have been widely studied in the literature of …

The causal modelling of Bell experiments relies on three fundamental assumptions: locality,
freedom of choice and arrow-of-time. It turns out that nature violates Bell inequalities, which …

In this work we present a hierarchy of generalized contextuality. It refines the traditional
binary distinction between contextual and noncontextual theories, and facilitates their …

In a recent paper [Carcassi, Oldofredi and Aidala, Found Phys 54, 14 (2024)] it is claimed
that the whole Harrigan--Spekkens framework of ontological models is inconsistent with …

Empirical falsifiability of the predictions of physical theories is the cornerstone of the
scientific method. Physical theories attribute empirically falsifiable operational properties to …

A key aim of quantum foundations is to characterize the sense in which nature goes beyond
classical physics. Understanding nonclassicality is one of our best avenues towards finding …

Motivated by treating the 2→ 1 parity-oblivious multiplexing under the influence of
experimental noise, with its success probability serving as an indicator of nonclassicality …
