On the connection between mutually unbiased bases and orthogonal Latin squares (2009)
Paterek, T., Pawlowski, M., Grassl, M., Brukner, C.
We offer a piece of evidence that the problems of finding the number of mutually unbiased bases (MUB) and mutually orthogonal Latin squares (MOLS) might not be equivalent. We study a particular...
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...
On setting and outcome (in)dependence in Bell experiments (2009)
Pawlowski, M., Kofler, J., Paterek, T., Brukner, C.
We study what kind of information--i.e. about the distant measurement setting or the outcome or both--and which amount of it has to be transferred from one laboratory to a distant one to simulate the...
Experimentally friendly geometrical criteria for entanglement (2007)
Badziag, P., Brukner, C., Laskowski, W., Paterek, T., Zukowski, M.
We present an intuitive geometrical entanglement criterion. It allows formulation of simple and experimentally friendly sufficient conditions for entanglement. The conditions are illustrated with...
Multiparticle Bell's inequalities involving many measurement settings (2003)
Brukner, C., Laskowski, W., Paterek, T., Zukowski, M.
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 inequalities. The...
