G. Brida et al., New experimental test of Bell inequalities by the use of a non-maximally entangled photon state, PHYS LETT A, 268(1-2), 2000, pp. 12-16
We report on the realisation of a new test of Bell inequalities using the s
uperposition of type I parametric down conversion produced in two different
non-linear crystals pumped by the same laser, but with different polarisat
ions.
We discuss the advantages and the possible developments of this configurati
