Discrimination of Non-Local Correlations [PDF]
Entropy, 2019 In view of the importance of quantum non-locality in cryptography, quantum computation, and communication complexity, it is crucial to decide whether a given correlation exhibits non-locality or not. As proved by Pitowski, this problem is NP-complete, and is thus computationally intractable unless NP is equal to P.

A histories perspective on characterizing quantum non-locality
New Journal of Physics, 2014 We introduce a framework for studying non-locality and contextuality inspired by the path integral formulation of quantum theory. We prove that the existence of a strongly positive joint quantum measure—the quantum analogue of a joint probability measure—

Quantum Contextuality with Stabilizer States
Entropy, 2013 The Pauli groups are ubiquitous in quantum information theory because of their usefulness in describing quantum states and operations and their readily understood symmetry properties.

Device-independent certification of one-shot distillable entanglement
New Journal of Physics, 2019 Entanglement sources that produce many entangled states act as a main component in applications exploiting quantum physics such as quantum communication and cryptography. Realistic sources are inherently noisy, cannot run for an infinitely long time, and

Non-Local Parity Measurements and the Quantum Pigeonhole Effect
Entropy, 2018 The pigeonhole principle upholds the idea that by ascribing to three different particles either one of two properties, we necessarily end up in a situation when at least two of the particles have the same property.

Causal structures from entropic information: geometry and novel scenarios
New Journal of Physics, 2014 Bell's theorem in physics, as well as causal discovery in machine learning, both face the problem of deciding whether observed data is compatible with a presumed causal relationship between the variables (for example, a local hidden variable model ...

Non-Abelian Topological Approach to Non-Locality of a Hypergraph State
Entropy, 2015 We present a theoretical study of new families of stochastic complex information modules encoded in the hypergraph states which are defined by the fractional entropic descriptor.

Conditions for the confirmation of three-particle non-locality [PDF]
, 2002 The notion of genuine three-particle non-locality introduced by Svetlichny \cite{Svetlichny} is discussed. Svetlichny's inequality which can distinguish between genuine three-particle non-locality and two-particle non-locality is analyzed by ...

Causal non-locality can arise from constrained replication [PDF]
, 2015 The fundamental theories of physics are local theories, depending on local interactions of local variables. It is not clear if and how strictly local theories can produce non-local variables that have causal effectiveness.

Bound non-locality and activation
, 2010 We investigate non-locality distillation using measures of non-locality based on the Elitzur-Popescu-Rohrlich decomposition. For a certain number of copies of a given non-local correlation, we define two quantities of interest: (i) the non-local cost ...
