Abstract

We propose two schemes to generate multiqubit GHZ states and W-class states in circuit QED. The schemes only need one step, and the operation times do not increase with the growth of the qubit number. Due to the virtual excitations of the resonator, the procedures are insensitive to the decay of the resonator. Numerical analysis shows that the schemes can be implemented with high fidelities. The schemes are suitable for large number of qubits under currently feasible circuit QED parameters.
