Triple photons
Résumé
Triple photon generation (TPG)is based on a third-order nonlinear optical interaction, which is the most direct way to produce pure quantum three-photon states. These states can exhibit three-body quantum entanglement and their statistics go beyond the usual Gaussian statistics of coherent sources and optical parametric twin-photon generators, offering new tools for quantum mechanics(Fig. 1 –left).Furthermore, from the application point of view, the generation of entangled photon pairs heralded by the detection of a third photon can be used in advanced quantum communication protocols.We made the first experimental demonstration of TPG in 2004 using a bi-stimulation schemein a bulk KTiOPO4(KTP)crystal[1], followed by the quantum theory [2,3].
