Do all pure entangled states violate Bell's inequalities for correlation functions?
Marek Zukowski, Caslav Brukner, Wieslaw Laskowski +1
Any pure entangled state of two particles violates a Bell inequality for two-particle correlation functions (Gisin's theorem). We show that there exist pure entangled N>2 qubit sta…
Greenberger-Horne-Zeilinger paradoxes for N quNits
Dagomir Kaszlikowski, Marek Zukowski
In this paper we show the series of Greenberger-Horne-Zeilinger paradoxes for N maximally entangled N-dimensional quantum systems.
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…
The essence of entanglement
Caslav Brukner, Marek Zukowski, Anton Zeilinger
Entanglement, according to Erwin Schroedinger the essence of quantum mechanics, is at the heart of the Einstein-Podolsky-Rosen paradox and of the so called quantum-nonlocality - th…
Clauser-Horne inequality for qutrits
Dagomir Kaszlikowski, L. C. Kwek, Jing-Ling Chen +2
In this brief report we show the new Bell-Clauser-Horne inequality for two entangled three dimensional quantum systems (so called qutrits). This inequality is violated by a maximal…
Entangled qutrits violate local realism stronger than qubits - an analytical proof
Jing-Ling Chen, Dagomir Kaszlikowski, L. C. Kwek +2
In Kaszlikowski [Phys. Rev. Lett. {\bf 85}, 4418 (2000)], it has been shown numerically that the violation of local realism for two maximally entangled -dimensional ()…
