Output of multiphoton entangled states with cavity QED
Jie-Hui Huang, Shi-Yao Zhu · Physical Review A · 2006
A scheme for the output of an Einstein-Podolsky-Rosen entangled photon pair is proposed in a cavity QED system composed of two high $Q$ cavities and a moving atom passing through them and with a final detection on the atomic ground states. The theoretical derivation shows that the production of multientangled photons can be achieved by passing the atom through additional cavities along the atom's path.
