中文摘要：

为在连续的量测量下面的任何目标贝尔状态的准备，这纸建议完成控制的一个方法由在二个不同模型之间切换或由不到一个在二条控制隧道之间切换客观模型。合适的控制 Hamiltonians 被选择因为二个系统当模特儿，切换的策略在之间二当模特儿被设计，并且整个切换的系统的稳定性在理论被证明。因为一只给定的目标钟州，建议切换的有效性在不同模型之间的控制策略通过模拟实验被说明。

英文摘要：

For the preparation of any target Bell state under continuous quantum measurement, this paper proposes a method which achieves the control objective by switching between two different models or by switching between two control channels under one model. Proper control Hamiltonians are selected for the two system models, a switching strategy between the two models is designed, and the stability of the whole switching system is proved in theory. For a given target Bell state, the effectiveness of the proposed switching control strategy between different models is illustrated through simulation experiments.
