摘　　要：A scheme is proposed to generate W state with qubits of superconducting quantum interference devices （SQUIDs）, based on adiabatic passage along dark state. Taking advantages of adiabatic passage, the scheme is very robust against decoherence, and it does not need to control the classical field and the interaction time accurately. Because of the achievable strong coupling between SQUID qubits and cavity, W state can be generated with high successful probability.
