We propose a way for realizing N-qubit controlled-U gate with superconducting quantum interference de-vices( SQUID) coupled to a supercondcting resonator. In this proposal,the two lowest levels of each SQUID serve as the logical states and two intermediate levels of each SQUID are used as auxiliary sates. A high speed N-qubit con-trolled-U gate can be realized by SQUID-resonator resonant interaction and SQUID-resonator large detuning interac-tion.
