Device-independent quantum key distribution secure against collective attacks
Stefano Pironio, Antonio Acin, Nicolas Brunner +3
Device-independent quantum key distribution (DIQKD) represents a relaxation of the security assumptions made in usual quantum key distribution (QKD). As in usual QKD, the security…
Quantifying multipartite nonlocality
Jean-Daniel Bancal, Cyril Branciard, Nicolas Gisin +1
The nonlocal correlations of multipartite entangled states can be reproduced by a classical model if sufficiently many parties join together or if sufficiently many parties broadca…
Quantum experiments with human eyes as detectors based on cloning via stimulated emission
Pavel Sekatski, Nicolas Brunner, Cyril Branciard +2
We show theoretically that the multi-photon states obtained by cloning single-photon qubits via stimulated emission can be distinguished with the naked human eye with high efficien…
