A new physical principle: Information Causality (2009)
Pawlowski, M., Paterek, T., Kaszlikowski, D., Scarani, V., Winter, A., Zukowski, M.
Quantum physics exhibits many remarkable features. For example, it gives probabilistic predictions (non-determinism), does not allow copying of unknown states (no-cloning), its correlations are...
Controllable Quantum Switchboard (2007)
Kaszlikowski, D., Kwek, L. C., Lai, C. H., Vedral, V.
All quantum information processes inevitably requires the explicit state preparation of an entangled state. Here we present the construction of a quantum switchboard which can act both as an optimal...
Local extraction of EPR entanglement from classical systems (2006)
Coherent states with large amplitudes are traditionally thought of as the best quantum mechanical approximation of classical behavior. Here we argue that, far from being classical, coherent state are...
Multi-Component Bell Inequality and its Violation for Continuous Variable Systems (2003)
Chen, Jing-Ling, Wu, Chunfeng, Kwek, L. C., Kaszlikowski, D., Zukowski, M., Oh, C. H.
Multi-component correlation functions are developed by utilizing d-outcome measurements. Based on the multi-component correlation functions, we propose a Bell inequality for bipartite d-dimensional...
Three qubit GHZ correlations and generalised Bell experiments (2003)
Kaszlikowski, D., Zukowski, M.
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. Finally we shall...
Kiesel, N., Bourennane, Mohamed, Kurtsiefer, C., Weinfurter, Harald, Kaszlikowski, D., Laskowski, W., ...
The thesis is divided into three parts. In the first part a new theoretical analysis of interferometric experiments by Alley-Shih, Ou-Mandel and the entanglement swapping experiment is performed. It...
Violations of local realism by two entangled quNits are stronger than for two qubits (2000)
Kaszlikowski, D., Gnacinski, P., Zukowski, M., Miklaszewski, W., Zeilinger, A.
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 defined in an...
