Detecting genuine multipartite quantum non-locality -- a simple approach and generalization to arbitrary dimension
Jean-Daniel Bancal, Nicolas Brunner, Nicolas Gisin +1
The structure of Bell-type inequalities detecting genuine multipartite non-locality, and hence detecting genuine multipartite entanglement, is investigated. We first present a simp…
Looking for symmetric Bell inequalities
Jean-Daniel Bancal, Nicolas Gisin, Stefano Pironio
Finding all Bell inequalities for a given number of parties, measurement settings, and measurement outcomes is in general a computationally hard task. We show that all Bell inequal…
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…
Practical private database queries based on a quantum key distribution protocol
Markus Jakobi, Christoph Simon, Nicolas Gisin +4
Private queries allow a user Alice to learn an element of a database held by a provider Bob without revealing which element she was interested in, while limiting her information ab…
