Necessary detection efficiencies for secure quantum key distribution and bound randomness
Antonio Acín, Daniel Cavalcanti, Elsa Passaro +2
In recent years, several hacking attacks have broken the security of quantum cryptography implementations by exploiting the presence of losses and the ability of the eavesdropper t…
Optimal randomness certification in the quantum steering and prepare-and-measure scenarios
Elsa Passaro, Daniel Cavalcanti, Paul Skrzypczyk +1
Quantum mechanics predicts the existence of intrinsically random processes. Contrary to classical randomness, this lack of predictability can not be attributed to ignorance or lack…
Joining and splitting the quantum states of photons
Elsa Passaro, Chiara Vitelli, Nicolo' Spagnolo +3
A photonic process named as "quantum state joining" has been recently experimentally demonstrated [C. Vitelli et al., Nature Photon. 7, 521 (2013)] that corresponds to the transfer…
Detection loophole attacks on semi-device-independent quantum and classical protocols
Michele Dall'Arno, Elsa Passaro, Rodrigo Gallego +2
Semi-device-independent quantum protocols realize information tasks - e.g. secure key distribution, random access coding, and randomness generation - in a scenario where no assumpt…
Robustness of Device Independent Dimension Witnesses
Michele Dall'Arno, Elsa Passaro, Rodrigo Gallego +1
Device independent dimension witnesses provide a lower bound on the dimensionality of classical and quantum systems in a "black box" scenario where only correlations between prepar…
