Entanglement swapping for generalized non-local correlations
Tony Short, Sandu Popescu, Nicolas Gisin
We consider an analogue of entanglement-swapping for a set of black boxes with the most general non-local correlations consistent with relativity (including correlations which are…
Generalised Asymmetric Quantum Cloning
S. Iblisdir, A. Acin, N. Gisin
We study machines that take N identical replicas of a pure qudit state as input and output a set of M_A clones of a given fidelity and another set of clones of another fideli…
The physics of no-bit-commitment : Generalized quantum non-locality versus oblivious transfer
Tony Short, Nicolas Gisin, Sandu Popescu
We show here that the recent work of Wolf and Wullschleger (quant-ph/0502030) on oblivious transfer apparently opens the possibility that non-local correlations which are stronger…
How come the Correlations?
Nicolas Gisin
In relativity there is space-time out there. In quantum mechanics there is entanglement. Entanglement manifests itself by producing correlations between classical events (e.g. the…
Towards practical and fast Quantum Cryptography
Nicolas Gisin, Gregoire Ribordy, Hugo Zbinden +3
We present a new protocol for practical quantum cryptography, tailored for an implementation with weak coherent pulses. The key is obtained by a very simple time-of-arrival measure…
Superluminal hidden communication as the underlying mechanism for quantum correlations: constraining models
Valerio Scarani, Nicolas Gisin
Since Bell's theorem, it is known that quantum correlations cannot be described by local variables (LV) alone: if one does not want to abandon classical mechanisms for correlations…
