Quantifying Bell: The resource theory of nonclassicality of common-cause boxes
We take a resource-theoretic approach to the problem of quantifying nonclassicality in Bell
scenarios. The resources are conceptualized as probabilistic processes from the setting …

The type-independent resource theory of local operations and shared randomness
In space-like separated experiments and other scenarios where multiple parties share a
classical common cause but no cause-effect relations, quantum theory allows a variety of …

Genuine network quantum nonlocality and self-testing
The network structure offers in principle the possibility for novel forms of quantum nonlocal
correlations, that are proper to networks and cannot be traced back to standard quantum …

Genuine multipartite nonlocality is intrinsic to quantum networks
Quantum entanglement and nonlocality are inextricably linked. However, while
entanglement is necessary for nonlocality, it is not always sufficient in the standard Bell …

Resource theory of entanglement with a unique multipartite maximally entangled state
Entanglement theory is formulated as a quantum resource theory in which the free
operations are local operations and classical communication (LOCC). This defines a partial …

Quantifying Bell nonlocality with the trace distance
Measurements performed on distant parts of an entangled quantum state can generate
correlations incompatible with classical theories respecting the assumption of local …

Fundamental limits on key rates in device-independent quantum key distribution
In this paper, we introduce intrinsic non-locality and quantum intrinsic non-locality as
quantifiers for Bell non-locality, and we prove that they satisfy certain desirable properties …

Neither contextuality nor nonlocality admits catalysts
M Karvonen - Physical Review Letters, 2021 - APS
We show that the resource theory of contextuality does not admit catalysts, ie, there are no
correlations that can enable an otherwise impossible resource conversion and still be …

Noncontextual wirings
Contextuality is a fundamental feature of quantum theory necessary for certain models of
quantum computation and communication. Serious steps have therefore been taken towards …
