Resumen:
An event-ready sor deterministicd source of entangled states is of interest in the practical implementation of
schemes of quantum computation and cryptography as well as in the experiments aimed to elucidate the
foundations of quantum mechanics. I study the phase matching geometry and detection conditions for the
process of three-photon frequency down-conversion, which is a possible source of that kind. It is apparently
free of some limitations of the schemes based on two-photon frequency down-conversion. The goal of the
proposed setup is not the generation of an entangled state of three photons sin a GHZ-state sensed, but of an
entangled state of two photons with a trigger signal. As an example, I estimate the values of the trios flux
and triggers reliability for the particular case of crystal calcite illuminated by the fourth harmonic of a
Nd:YAG mode-locked laser.sor deterministicd source of entangled states is of interest in the practical implementation of
