摘要：
Geometric phases are studied in terms of invariant operator for a time-dependent superconducting qubit. The results show that the geometric phase depends on the dipole interaction strength between the qubit and a microwave field of frequency and phase, which provides a clue to realize the geometric quantum computation in the experiments.
