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 …

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 …

A well-motivated method for demonstrating that an experiment resists any classical
explanation is to show that its statistics violate generalized noncontextuality. We here …

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 the operational predictions of quantum theory conflict
with a classical worldview, it is necessary to articulate a notion of classicality within an …

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

It is a fundamental prediction of quantum theory that states of physical systems are
described by complex vectors or density operators on a Hilbert space. However, many …

We consider the problem of entanglement-assisted one-shot classical communication. In the
zero-error regime, entanglement can increase the one-shot zero-error capacity of a family of …

The gold standard for demonstrating that an experiment resists any classical explanation is
to show that its statistics violate generalized noncontextuality. We here provide an open …
