A central result in the foundations of quantum mechanics is the Kochen-Specker theorem. In
short, it states that quantum mechanics is in conflict with classical models in which the result …

Kirkwood-Dirac representations of quantum states are increasingly finding use in many
areas within quantum theory. Usually, representations of this sort are only applied to provide …

To make precise the sense in which nature fails to respect classical physics, one requires a
formal notion of classicality. Ideally, such a notion should be defined operationally, so that it …

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} …

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 …

Generalisation in machine learning often relies on the ability to encode structures present in
data into an inductive bias of the model class. To understand the power of quantum machine …

Weak values are quantities accessed through quantum experiments involving weak
measurements and postselection. It has been shown that “anomalous” weak values (those …

We discuss the role of contextuality within quantum fluctuation theorems, in the light of a
recent no-go result by Perarnau-Llobet et al. We show that any fluctuation theorem …

To make precise the sense in which the operational predictions of quantum theory conflict
with a classical worldview, it is necessary to articulate a notion of classicality within an …

The notion of macrorealism was introduced by Leggett and Garg in an attempt to capture our
intuitive conception of the macroscopic world, which seems difficult to reconcile with our …
