摘      要：A fast scheme to generate Greenberger-Horne-Zeilinger states between different cavities in circuit QED systems is *** implement this scheme,we design a feasible experimental device with three qubits and three *** this device,all the couplings between qubit and qubit,cavity and qubit are tunable and are independent with frequencies,and thus the shortcut to adiabaticity technique can be directly applied in our *** is demonstrated that the GHZ state can be generated rapidly with high fidelity in our scheme.
