Device-independent certification of two bits of randomness from one entangled bit and Gisin's elegant Bell inequality
Ole Andersson, Piotr Badziąg, Irina Dumitru +1
We prove that as conjectured by Ac\'ın et al. [Phys. Rev. A 93, 040102(R) (2016)], two bits of randomness can be certified in a device-independent way from one bit of entanglement…

Self-testing properties of Gisin's elegant Bell inequality
Ole Andersson, Piotr Badziąg, Ingemar Bengtsson +2
An experiment in which the Clauser-Horne-Shimony-Holt inequality is maximally violated is self-testing (i.e., it certifies in a device-independent way both the state and the measur…
