Information causality is a physical principle which states that the amount of randomly accessible data over a classical communication channel cannot exceed its capacity, even if the sender and the receiver have access to a source of nonlocal correlations. This principle can be used to bound the nonlocality of quantum mechanics without resorting to its full formalism, with a notable example of reproducing the Tsirelson's bound of the Clauser-Horne-Shimony-Holt inequality. Despite being promising…

Quantum Bell inequalities from Information Causality - tight for Macroscopic Locality

This work presents a family of inequalities, which approximate the set of quantum correlations in Bell scenarios where the number of settings or outcomes can be arbitrary, and derives these inequalities from the principle of Information Causality, and thus does not assume the formalism of quantum mechanics.

Principle of information causality rationalizes quantum composition

Anchoring the abstract mathematical formulation of Hilbert space quantum mechanics on physical ground is one of the long standing pursuits of quantum foundational research. Here we show that the

Distilling nonlocality in quantum correlations

This work identifies a protocol, namely logical OR-AND wiring, that can distil nonlocality to significantly high degree starting from arbitrarily weak quantum nonlocal correlations, and demonstrates the importance of this wiring in detecting post quantum correlations.
