Generation of n-Atom GHZ State via Two-sided Cavity QED
Faqiang Wang · ACTA PHOTONICA SINICA · 2009
The scheme was proposed to generate multiple-atom GHZ state via the state-of-the-art two-sided cavities.A single-photon pulse could not only be reflected but also be transmitted through the two-sided cavity with a single trapped atom,which is in certain state.Entanglement between the trapped atom and the input field was resulted in this property.The numerical simulations showed that the produced multiple-particle GHZ state had high fidelity and success probability.The intrinsic noise,such as the atomic spontaneous emission,only led to the error probability and had no influence on the fidelity.In addition,the high-Q cavity and the Lamb-Dicke condition of atom were not required,which expanded the possibility of experimental realization.
