Extending the class of quantum states that do not allow local realistic description
Wieslaw Laskowski, Tomasz Paterek, Marek Zukowski
We present the necessary and sufficient condition for the violation of a new series of multipartite Bell's inequalities with many measurement settings.
Entanglement swapping of noisy states: A kind of superadditivity in nonclassicality
Aditi Sen De, Ujjwal Sen, Caslav Brukner +2
We address the question as to whether an entangled state that satisfies local realism will give a violation of the same, after entanglement swapping in a suitable scenario. We cons…
Multi-Component Bell Inequality and its Violation for Continuous Variable Systems
Jing-Ling Chen, Chunfeng Wu, L. C. Kwek +3
Multi-component correlation functions are developed by utilizing d-outcome measurements. Based on the multi-component correlation functions, we propose a Bell inequality for bipart…
Output state in multiple entanglement swapping
Aditi Sen De, Ujjwal Sen, Marek Zukowski
The technique of quantum repeaters is a promising candidate for sending quantum states over long distances through a lossy channel. The usual discussions of this technique deals wi…
Multiparticle Bell's inequalities involving many measurement settings
C. Brukner, W. Laskowski, T. Paterek +1
We present a prescription for obtaining Bell's inequalities for N>2 observers involving more than two alternative measurement settings. We give examples of some families of such in…
Three qubit GHZ correlations and generalised Bell experiments
D. Kaszlikowski, M. Zukowski
We present a brief historical introduction to the topic of Bell's theorem. Next we present the surprising features of the three particle Greenberger-Horne-Zeilinger (GHZ) states. F…
