We investigate a scheme to improve the precision of parameter estimation using no-knowledge measurement-based feedback control. The scheme shows that combination of no-knowledge measurement-based feedback control and quantum weak measurement is the o

Geometric phase of mixed state is investigated for three-level system obeying a high-temperature master equation. The results show the Berry phase of mixed phase is strongly dependent on the initial condition. For the different initial angle, the tur

Pancharatnam phase and Berry phase are investigated and compared for a three-level atom crosses a double cavity with two near resonant fields. The results show that the time-dependent Pancharatnam phase shows a transitive phenomenon during the evolvi

A strategy is investigated to overcome the decoherence for open quantum system by controlling external parameters. The results show that output state may be a pure state in some critical magnetic field parameters which depend on the decay rates so th
