Anisotropically high entanglement of biphotons generated in spontaneous parametric down conversion
M. V. Fedorov, M. A. Efremov, P. A. Volkov +3
We show that the wave packet of a biphoton generated via spontaneous parametric down conversion is strongly anisotropic. Its anisotropic features manifest themselves very clearly i…

Realization of four-state qudits using biphotons
E. V. Moreva, G. A. Maslennikov, S. S. Straupe +1
The novel experimental realization of four-level optical quantum systems (ququarts) is presented. We exploit the polarization properties of frequency non-degenerate biphoton field…
