Maximal randomness from partially entangled states
Erik Woodhead, Jędrzej Kaniewski, Boris Bourdoncle +4
We investigate how much randomness can be extracted from a generic partially entangled pure state of two qubits in a device-independent setting, where a Bell test is used to certif…
Quantifying the randomness of copies of noisy Popescu-Rohrlich correlations
Boris Bourdoncle, Stefano Pironio, Antonio Acin
In a no-signaling world, the outputs of a nonlocal box cannot be completely predetermined, a feature that is exploited in many quantum information protocols exploiting non-locality…
Randomness versus nonlocality in the Mermin-Bell experiment with three parties
Erik Woodhead, Boris Bourdoncle, Antonio Acín
The detection of nonlocal correlations in a Bell experiment implies almost by definition some intrinsic randomness in the measurement outcomes. For given correlations, or for a giv…
Regularising data for practical randomness generation
Boris Bourdoncle, Pei-Sheng Lin, Denis Rosset +2
Non-local correlations that obey the no-signalling principle contain intrinsic randomness. In particular, for a specific Bell experiment, one can derive relations between the amoun…
