Abstract：

We　report　a　scheme　for　implementing　a　multiqubit　quantum　phase　gate　in　a　neutral　atomic　ensemble　via　an　asymmetric　Rydberg　blockade.　The　multiqubit　gate　is　successfully　realized　by　following　a　three-step　approach.　The　neutral-atom　qubits　are　always　illuminated　by　the　common　laser　beams　and　therefore　individual　addressing　of　the　atoms　is　not　required.　The　gate　errors　induced　by　atomic　spontaneous　emission,　imperfect　excitation　blockade,　and　atomic　motion　are　discussed.　©　2010　The　American　Physical　Society.
