摘要
研究了玻色-爱因斯坦凝聚体(BEC)N粒子体系在最短时间内制备最大纠缠态的相关规律。我们采用玻色-爱因斯坦凝聚体(BEC)两模模型进行研究,探讨了全同粒子系统粒子间相互作用参数c对制备最大纠缠态所需的最短时间的影响;进而讨论了制备最大纠缠态所需的最短时间tmin与系统粒子数N的关系,以及此时系统参数c的取值范围和特点。
This paper mainly exploit two-mode model to investigate some rules on creating the maximally entangled, state of identical particles system within the shortest time. It investigates the influence of the value of the shortest time for creating the maximally entangled state of identical particles system with finite number of particles and presents the range of e in which the shortest creation time is needed. Furthermore, it studies the relationship between the shortest creating time, the range of e and the number of particles of the system.
