Popis: We propose a feasible experimental scheme to demonstrate the geometric phase in flux qubits by means of a detuning coherent microwave pulse technique. Furthermore, controlled phase shift gates can be implemented based on the geometric phases by inductance coupling of two flux qubits. There are limitations under the adiabatic condition, but due to its geometric nature, the scheme might have an important application in precise preparation quantum state such as the initial state of decoherence-free subspace (DFS).
