Gaussian states have played an important role in the physics of continuous-variable
quantum systems. They are appealing for the experimental ease with which they can be …

Quantum computers promise considerable speedups with respect to their classical
counterparts. However, the identification of the innately quantum features that enable these …

Operational contextuality forms a rapidly developing subfield of quantum information theory.
However, the characterization of the quantum mechanical entities that fuel the phenomenon …

Negativity of the Wigner function is arguably one of the most striking non-classical features
of quantum states. Beyond its fundamental relevance, it is also a necessary resource for …

Contextuality is a feature of quantum correlations. It is crucial from a foundational
perspective as a non-classical phenomenon, and from an applied perspective as a resource …

Recent theories developing broad notions of context and its effects on inference are
becoming increasingly important in fields as diverse as cognitive psychology, information …

This chapter contains an exposition of the sheaf-theoretic framework for contextuality
emphasising resource-theoretic aspects, as well as some original results on this topic. In …

Reliable randomness is a core ingredient in algorithms and applications ranging from
numerical simulations to statistical sampling and cryptography. The outcomes of …

Extended Wigner's friend no-go theorems provide a modern lens for investigating the
measurement problem, by making precise the challenges that arise when one attempts to …

A review is made of the field of contextuality in quantum mechanics. We study the historical
emergence of the concept from philosophical and logical issues. We present and compare …
