| Abstract: | 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. |
