Preparation of a maximally entangled state of twoladder-type three-level atoms having different coupling constant with the cavity
Jin Xing-Ri · Journal of Yanbian University · 2004
We propose a scheme to prepare a maximally entangled state of two ladder-type three-level atoms with have difference coupling constant with a non-resonant thermal cavity and driven by the external strong classical flied. Because of the external driven strong classical flied, the photon-number-dependent parts in the effective Hamiltonian are canceled. The advantage of scheme is that the cavity may be in any state.
