Abstract
We propose a simple scheme to implement multi-qubit quantum Grover search with atomic ensembles by adiabatic passage. The scheme is immune to the atomic spontaneous emission, cavity decay and fiber decay. Furthermore, the process can be speeded up with atomic ensemble instead of single atom, which is important in view of decoherence. With each atomic ensemble confined in an individual cavity, our scheme is experimentally scalable to multi-qubit cases.
