How quantum correlations enhance prediction of complementary measurements (2004)
Filip, R., Gavenda, M., Soubusta, J., Cernoch, A., Dusek, M.
If there are correlations between two qubits then the results of the measurement on one of them can help to predict measurement results on the other one. It is an interesting question what can be...
