中文摘要：

在时间依赖者相互作用导致的一个合成系统的果浆阶段被讨论。我们作为合成系统选二为联合 spin-1/2 系统：分系统之一受到一个静态的磁场，并且在二旋转之间的联合参数及时是可控制的。我们证明时间依赖者相互作用能作为那以一个类似的方法导致果浆阶段一个 spin-1/2 系统(qubit ) 被一个有效时间依赖者磁场驾驶。而且，与静态的磁场以及反面的相反的方向使用二个连续周期联合参数签名，重要 two-qubit 单一的转变基于完全，果浆阶段能被构造。

英文摘要：

The Berry phase in a composite system induced by the time-dependent interaction is discussed. We choose two coupled spin-1/2 systems as the composite system： one of the subsystems is subjected to a static magnetic field, and the coupling parameters between two spins are controllable in time. We show that the time-dependent interaction can induce the Berry phase in a similar way as that a spin-1/2 system （qubit） is driven by an effective time-dependent magnetic field. Furthermore, using two consecutive cycles with opposite directions of both the static magnetic field as well as opposite signs of the coupling parameters, a nontrivial two-qubit unitary transformation purely based on Berry phases can be constructed.
