| Résumé : | A protocol is said to be device-independent when the level of its performance can be inferred without making any assumptions regarding the inner workings of the apparatus used to implement it. In this paper we introduce a device-independent weak coin flipping protocol based on a single GHZ test. Interestingly, the protocol calls for the exchange of (quantum) systems between participants; a feature which is not trivial to incorporate in a device-independent setting where a system's behavior may depend on the time, location, and its history. Alice's and Bob's maximal cheating probabilities are given by ≈ 0.974 and cos2 (π/ 8) ≈ 0.854. © 2014 Springer-Verlag Berlin Heidelberg. |
