On the local and non-local content of bipartite qubit and qutrit correlations
Valerio Scarani
The local and non-local contents of non-local probability distributions are studied using the approach of Elitzur, Popescu and Rohrlich [Phys. Lett. A \textbf{162}, 25 (1992)]. Thi…
Experimental Falsification of Leggett's Non-Local Variable Model
Cyril Branciard, Alexander Ling, Nicolas Gisin +3
Bell's theorem guarantees that no model based on local variables can reproduce quantum correlations. Also some models based on non-local variables, if subject to apparently "reason…
Quantum cryptography with finite resources: unconditional security bound for discrete-variable protocols with one-way post-processing
Valerio Scarani, Renato Renner
We derive a bound for the security of QKD with finite resources under one-way post-processing, based on a definition of security that is composable and has an operational meaning.…
Entangling Independent Photons by Time Measurement
Matthaeus Halder, Alexios Beveratos, Nicolas Gisin +3
A quantum system composed of two or more subsystems can be in an entangled state, i.e. a state in which the properties of the global system are well defined but the properties of e…
Detection loophole in asymmetric Bell experiments
Nicolas Brunner, Nicolas Gisin, Valerio Scarani +1
The problem of closing the detection loophole with asymmetric systems, such as entangled atom-photon pairs, is addressed. We show that, for the Bell inequality I_3322, a minimal de…
Device-independent security of quantum cryptography against collective attacks
Antonio Acin, Nicolas Brunner, Nicolas Gisin +3
We present the optimal collective attack on a Quantum Key Distribution (QKD) protocol in the "device-independent" security scenario, where no assumptions are made about the way the…
