Experimental Generation of Bright Three-Color Tripartite Entanglement

Quantum information technology will require quantum networks to send information from one place to another. If we consider present day candidates for pieces of quantum hardware, we immediately realize that each have strengths and weaknesses. One can thus envisage hybrid systems, combining strengths of different hardware, which can interact with light at different frequencies. We have been investigating the generation of multipartite multicolor entanglement between bright beams of light, emitted by an optical parametric oscillator. In this talk, I will describe our very recent experimental demonstration of three-color tripartite entanglement.
