Generation of Cluster States in Cavity QED
Zhou Yan-Li, Yang Li-Jia, Hong‐Yi Dai · Chinese Physics Letters · 2007
We propose two schemes for the generation of cluster states in the context of cavity quantum electrodynamics (QED). In the first scheme, we prepare multi-cavity cluster states with information encoded in the coherent states. The second scheme is to generate multi-atom cluster states, where qubits are represented by the states of cascade Rydberg atoms. Both the schemes are based on the atom-cavity interaction and the atomic spontaneous radiation can be efficiently reduced since the cavity frequency is largely detuned from the atomic transition frequency.
