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…
Photon Echo Quantum Memory for Arbitrary Non-Stationary Light Fields
S. A. Moiseev, C. Simon, N. Gisin
We develop the theory of an optical quantum memory protocol based on the three pulse photon echo (PE) in an optically dense medium with controlled reversible inhomogeneous broadeni…
No nonlocal box with uniform outputs is universal
Frédéric Dupuis, Nicolas Gisin, André Allan Méthot
We show that standard nonlocal boxes, also known as Popescu-Rohrlich machines, are not sufficient to simulate any nonlocal correlations that do not allow signalling. This was known…
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…
