A versatile construction of Bell inequalities for the multipartite scenario
Florian J. Curchod, Mafalda L. Almeida, Antonio Acín
Local measurements acting on entangled quantum states give rise to a rich correlation structure in the multipartite scenario. We introduce a versatile technique to build families o…
Guess your neighbour's input: no quantum advantage but an advantage for quantum theory
Antonio Acín, Mafalda L. Almeida, Remigiusz Augusiak +1
Quantum mechanics dramatically differs from classical physics, allowing for a wide range of genuinely quantum phenomena. The goal of quantum information is to understand informatio…
Information Causality and Extremal Tripartite Correlations
Tzyh Haur Yang, Daniel Cavalcanti, Mafalda Almeida +2
We study the principle of information causality for the set of extremal correlations in the tripartite scenario. We show that all but one nonlocal extremal correlations in this sce…
Quantum networks reveal quantum nonlocality
D. Cavalcanti, M. L. Almeida, V. Scarani +1
The results of local measurements on some composite quantum systems cannot be reproduced classically. This impossibility, known as quantum nonlocality, represents a milestone in th…
Guess your neighbour's input: a multipartite non-local game with no quantum advantage
M. L. Almeida, J. -D. Bancal, N. Brunner +3
We present a multipartite nonlocal game in which each player must guess the input received by his neighbour. We show that quantum correlations do not perform better than classical…
Multipartite fully-nonlocal quantum states
Mafalda L. Almeida, Daniel Cavalcanti, Valerio Scarani +1
We present a general method to characterize the quantum correlations obtained after local measurements on multipartite systems. Sufficient conditions for a quantum system to be ful…
