Pseudo-telepathy: input cardinality and Bell-type inequalities
N. Gisin, A. A. Methot, V. Scarani
Pseudo-telepathy is the most recent form of rejection of locality. Many of its properties have already been discovered: for instance, the minimal entanglement, as well as the minim…
Zero-Error Attacks and Detection Statistics in the Coherent One-Way Protocol for Quantum Cryptography
Cyril Branciard, Nicolas Gisin, Norbert Lutkenhaus +1
This is a study of the security of the Coherent One-Way (COW) protocol for quantum cryptography, proposed recently as a simple and fast experimental scheme. In the zero-error regim…
Secrecy extraction from no-signalling correlations
Valerio Scarani, Nicolas Gisin, Nicolas Brunner +3
Quantum cryptography shows that one can guarantee the secrecy of correlation on the sole basis of the laws of physics, that is without limiting the computational power of the eaves…
Feats, Features and Failures of the PR-box
Valerio Scarani
One of the most intriguing features of quantum physics is the non-locality of correlations that can be obtained by measuring entangled particles. Recently, it has been noticed that…
An anomaly of non-locality
A. A. Methot, V. Scarani
Ever since the work of Bell, it has been known that entangled quantum states can rise non-local correlations. However, for almost forty years, it has been assumed that the most non…
