Abstract: (1546 Views)
In this paper we want to preserve the coherenceeffects in the interaction of a qubit with a single-mode field besides a reservoir via qubit frequency modulation, however, in the presence multi-photon (two- and four-photon) transitions. After introducing the model and a proper Hamiltonian, and solving the time-dependent Schrodinger equation, the probability amplitudes are obtained by which we plot the coherence effects in term of scaled time for different parameters. We show that the single- and two-photon the coherence process possess similar behavior, however, the decoherence effects in four-photon occurs inshorter times comparing with the two- (single-)photon transition.
