Constructive nonlocal games with very small classical values
M. Rosicka, S. Szarek, A. Rutkowski +2
There are few explicit examples of two player nonlocal games with a large gap between classical and quantum value. One of the reasons is that estimating the classical value is usua…
A note on bound entanglement and local realism
Dagomir Kaszlikowski, Marek Zukowski, Piotr Gnacinski
We show using a numerical approach that gives necessary and sufficient conditions for the existence of local realism, that the bound entangled state presented in Bennett et. al. Ph…
Violations of local realism by two entangled quNits are stronger than for two qubits
D. Kaszlikowski, P. Gnacinski, M. Zukowski +2
Tests of local realism vs quantum mechanics based on Bell's inequality employ two entangled qubits. We investigate the general case of two entangled quNits, i.e. quantum systems de…
