Quantum information is encoded into polarization states created by frequency-nondegenerate spontaneous parametric down-conversion in collinear geometry. In the scheme under analysis, the required nonorthogonal states are generated in a single nonlinear crystal. All states in the selected basis are measured deterministically. The results of initial experiments on transformation of the basis polarization states of a four-level optical system are discussed. © Pleiades Publishing, Inc., 2006.||Source Title:||Journal of Experimental and Theoretical Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/97579||ISSN:||10637761||DOI:||10.1134/S1063776106050037|
