利用偶极封锁机制制备多粒子W态
The Preparation of Multiparticle W State Via the Dipole Blockade Mechanism
摘要
Abstract
Based on collective encoding in an ensemble with 2N + 1 stable ground sates and N Rydberg states, we realize successfully the preparation of multiparticle W state via adjusting suitable interaction time between laser and ensemble and making use of the dipole blockade effect. The enco ding scheme effectively overcome the limit of qubit number caused by the dipole blockade effect be ing effective only within a certain range. Finally, we discuss the scheme's experimental feasibility.关键词
