В. Н. Горбачев, A. A. Rodichkina, A. I. Trubilko · Optics and Spectroscopy · 2005
Systems for preparing entangled states of light from biphotons on the basis of linear optical elements and projective measurements are considered. Specific features of quantum correlations of the appearing states can be detected in the proposed detection schemes.
