We　propose　a　scheme　to　generate　an　N　-qubit　cluster　state　by　adiabatic　passage　in　coupled　cavities.　The　required　interaction　time　keeps　unchanged　with　the　increasing　of　the　number　of　qubits　and　need　not　be　accurately　controlled.　In　addition,　the　scheme　is　robust　against　the　fluctuations　of　some　experimental　parameters.　©　2010　American　Institute　of　Physics.
