Abstract

We report the first experimental third order optical parametric generation The experimental setup leads to an efficient and pure cubic process. This result opens the way to quantum experiments on three-photon entanglement.

Third order nonlinear parametric optical interactions performed in bulk crystals or optical fibers lead to the generation of triple photons, which opens the way for new achievements in quantum optics and information.

Triple photons: a challenge in nonlinear and quantum optics

Kamel Bencheikh, Fabien Gravier, Julien Douady +2 more

This article is devoted to the generation and the quantum correlations of triple photons, which correspond to the creation of three highly correlated photons from the splitting of a single photon by a phase-matched third-order parametric nonlinear process. These triples constitute a Greenberger–Horne–Zeilinger state of light and are interesting from a fundamental point of view but also for new schemes of quantum cryptography. We give here the classical and quantum descriptions of triple photon generation, we report on the first experimental demonstration of such a generation, and we calculate the Wigner function of three-photon quantum states of light.

Triple photons and triple slits, a new frontier in quantum mechanics tests

Thomas D. Jennewein, Hannes Hübel, Deny R. Hamel +7 more

We will present our recent results in the generation of triple photons as well as triple slits, both providing interesting perspectives on the foundations of quantum mechanics and quantum optics. The creation of correlated triple photons [1] is a highly desirable process for research on quantum optics, novel states of three-photon entanglement, and applications in quantum information processing. It was proposed over 20 years ago, but considered impossible to perform given the low conversion efficiencies in non-linear optics. We recently managed to solve the technical challenges, and demonstrate a source for correlated photon triplets. Strikingly, the interferences of single photons passing through a triple slit can be useful for experimental verification of Born’s rule, which is at the heart of the formalism of quantum mechanics. We will illustrate the background of the argumentation, and show the elegant experimental setup, which allows this direct test of Born’s rule [2].

Experimental proposal for the generation of entangled photon triplets by third-order spontaneous parametric downconversion in optical fibers

María Corona, Karina Garay-Palmett, Alfred B. U’Ren

We present an experimental proposal for the generation of photon triplets based on third-order spontaneous parametric downconversion in thin optical fibers. Our analysis includes expressions for the quantum state, which describes the photon triplets and for the generation rate in terms of all experimental parameters. We also present, for a specific source design, numerically calculated generation rates.

Triple-photon generation: comparison between theory and experiment

Fabien Gravier, Benoı̂t Boulanger

We conceived an optical generator leading to the production of 3×1013 triple photons per pulse with a full-width duration of 88ps at 1/e2, by using a third-order optical parametric interaction phase-matched in a KTP crystal and pumped at 532 nm. The triple photon generation is stimulated by two photons orthogonally polarized emitted by a homemade optical parametric oscillator emitting at 1665 nm. The energy generated at 1474 nm is well modelized by an analytical model based on Jacobi elliptic functions. These results open the way to new quantum measurement relative to Greenberger-Horne-Zeilinger state of light.
