We propose a scheme for controlling the gradiometric flux qubit (GFQ) byapplying an ac bias current in a circuit-QED architecture. The GFQ isinsensitive to the magnetic flux fluctuations, which at the same time makes itchallenging to manipulate the qubit states by an external magnetic field. Inthis study, we demonstrate that an ac bias current applied to the$\alpha$-junction of the GFQ can control the qubit states. Further, the presentscheme is robust against the charge fluctuation as well as the magnetic fluxfluctuations, promising a long coherence time for quantum gate operations. Weintroduce a circuit-QED architecture to perform the single and two-qubitoperations with a sufficiently strong coupling strength.
