Generation of Atomic Greenberger–Horne–Zeilinger States Based on Faraday Rotation
Liang Hong-Hui, Xinghua Li · Communications in Theoretical Physics · 2010
Based on the input-output relation of the cavity and the Faraday Rotation mechanism, we propose a scheme for generating the n-atom Greenberger–Horne–Zeilinger state. In the scheme, the n-atom trapped respectively in n spatially separate cavities would be entangled with the photons going through the atom-cavity system. The successful probabilities of our protocol approach unity in the ideal case. What is more, no requirement for separately addressing further lowers experimental difficulties.
