Axiomatic approach to contextuality and nonlocality
Karol Horodecki, Andrzej Grudka, Pankaj Joshi +2
We present a unified axiomatic approach to contextuality and non-locality based on the fact that both are resource theories. In those theories the main objects are consistent boxes…
Bound on Bell Inequalities by Fraction of Determinism and Reverse Triangle Inequality
P. Joshi, K. Horodecki, M. Horodecki +5
It is an established fact that entanglement is a resource. Sharing an entangled state leads to non-local correlations and to violations of Bell inequalities. Such non-local correla…
Quantifying Contextuality
A. Grudka, K. Horodecki, M. Horodecki +5
Contextuality is central to both the foundations of quantum theory and to the novel information processing tasks. Although it was recognized before Bell's nonlocality, despite some…
No-broadcasting of non-signalling boxes via operations which transform local boxes into local ones
P. Joshi, A. Grudka, K. Horodecki +3
We deal with families of probability distributions satisfying non-signalling condition, called non-signalling boxes and consider class of operations that transform local boxes into…
