在本文中，我们考虑连续测量下双量子位系统的稳定性问题。我们的目标是稳定在量子信息技术中发挥重要作用的两种量子纠缠态。在本文中，我们证明通过连续输入在特定量子纠缠态下的全局稳定是可能的。通过数值模拟验证了控制输入的有效性。
In this paper, we consider a stabilization problem of a two-qubit system under continuous measurement. Our objective is to stabilize two types of quantum entangled state which play an important role in quantum information technology. In this paper, we show that the global stabilization at a specific quantum entangled state by continuous inputs is possible. An effectiveness of the control input is verified by numerical simulation.
