Device-independent certification of two bits of randomness from one entangled bit and Gisin's elegant Bell inequality
(American Physical Society, 2018-01-16)
We prove that as conjectured by Acín 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 using the maximal quantum violation of Gisin’s ...

Exponentially decreasing critical detection efficiency for any Bell inequality
(American Physical Society, 2022-11-30)
We address the problem of closing the detection efficiency loophole in Bell experiments, which is crucial for real-world applications. Every Bell inequality has a critical detection efficiency η that must be surpassed to ...
