We show that the resource theory of contextuality does not admit catalysts, i.e., there are no correlations that can enable an otherwise impossible resource conversion and still be recovered afterward. As a corollary, we observe that the same holds for nonlocality. As entanglement allows for catalysts, this adds a further example to the list of "anomalies of entanglement," showing that nonlocality and entanglement behave differently as resources. We also show that catalysis remains impossible…

The Sheaf-Theoretic Structure of Definite Causality
Also in the quantum theory one starts from certain numbers from which one deduces other numbers, which can be taken as initial numbers for a calculation in quantum theory.
Closing Bell: Boxing black box simulations in the resource theory of contextuality
This chapter contains an exposition of the sheaf-theoretic framework for contextuality emphasising resourcetheoretic aspects, as well as some original results on this topic. In particular, we


Noncontextual Wirings.
This work introduces noncontextual wirings: a class of contextuality-free operations with a clear operational interpretation and a friendly parametrization that complete a unified resource-theoretic framework for contextuality and Bell nonlocality.
Interconversion of nonlocal correlations
In this paper, we study the correlations that arise when two separated parties perform measurements on systems they hold locally. We restrict ourselves to those correlations with which arbitrarily
Effect Algebras, Presheaves, Non-locality and Contextuality
This paper starts with an effect algebraic approach to the study of non-locality and contextuality and defines a fully faithful embedding of the category of effect algebras in this presheaf category over the natural numbers.
No nonlocal box is universal
We show that standard nonlocal boxes, also known as Popescu-Rohrlich machines, are not sufficient to simulate any nonlocal correlations that do not allow signaling. This was known in the multipartite
A Combinatorial Approach to Nonlocality and Contextuality
AbstractSo far, most of the literature on (quantum) contextuality and the Kochen–Specker theorem seems either to concern particular examples of contextuality, or be considered as quantum logic. Here,
On nonlocality as a resource theory and nonlocality measures
With the advent of device-independent quantum information processing, nonlocality is nowadays regarded as a resource that can be used for various tasks. Using the analogy of entanglement theory, we
Nonlocality free wirings and the distinguishability between Bell boxes
Bell nonlocality can be formulated in terms of a resource theory with local-hidden variable models as resourceless objects. Two such theories are known, one built upon local operations assisted by
Popescu-Rohrlich correlations as a unit of nonlocality.
A set of nonlocal correlations that have come to be known as a Popescu-Rohrlich (PR) box suggest themselves as a natural unit of nonlocality, much as a singlet is a natural unit of entanglement. We
Nonlocal correlations as an information-theoretic resource
It is well known that measurements performed on spatially separated entangled quantum systems can give rise to correlations that are nonlocal, in the sense that a Bell inequality is violated. They
A comonadic view of simulation and quantum resources
It is shown that these morphisms capture notions of simulation between empirical models obtained via “free” operations in a resource theory of contextuality, including the type of classical control used in measurement-based quantum computation schemes.
