提出一种方案制备W态,方案基于暗态绝热过程.制备过程中,所有原子都处于基态,光纤模保持在真空态,在一定条件下可以忽略腔场激发,因此,方案非常抗消相干.方案的另一个优点是:只要满足绝热条件,不必要精确调节相互作用时间.方案成功的几率随原子数的增加而增加.

A scheme is proposed to generate a W state based on adiabatic passage along dark state.In the scheme,all the atoms are always in ground state,the field mode of the fiber remains in vacuum state,and the filed mode of the cavities being excited can be negligible under certain condition.Therefore,the scheme is very robust against decoherence.Another advantage of the scheme is that the interaction time does not need to be accurately adjusted as long as the adiabaticity condition is fulfilled.Furthermore,in the scheme,the successful probability increases with the increasing of atom number.
