Generation of four-particle GHZ states in bimodal cavity QED
杨贞标 · Chinese Physics · 2007
We propose a scheme for preparing four-particle Greenberger–Horne–Zeilinger states using two identical bimodal cavities, each supports two modes with different frequencies. This scheme is an alternative to another published work [Christopher C Gerry 1996 Phys. Rev. A 53 4591]. Comparisons between them are discussed. The fidelity and the probability of success influenced by cavity decay for the generated states are also considered.
