| Abstract: | By using the weak measurement and quantum measurement reversal method,we study the stabilization of a V-type three level quantum systems under the action of amplitude of dissipative decoherence.We get the analytic expressions of optimization conditions,fidelity and success rate.Through numerical simulation,we also find that when the strength of the weak measurement and quantum reversal measurement to meet certain conditions,the decoherence of the three level of quantum system could get effective and stable. |
