有限维量子马尔可夫主方程的能控性

Controllability properties for finite dimensional quantum Markovian master equations

C. Altafini

摘要:

从几何控制理论的各种概念被用来表征的行为的马尔可夫主方程的N-能级量子力学系统的酉控制驱动,并描述可达状态集的结构。证明了该系统是可达的,但既不是小时间可控的,也不是有限时间可控的。特别是,如果量子动力学半群的生成元是酉的,那么可达集在时间上单调增长时可以很容易地刻画。两个水平的情况下,详细处理。

英文摘要:

Various notions from geometric control theory are used to characterize the behavior of the Markovian master equation for N-level quantum mechanical systems driven by unitary control and to describe the structure of the sets of reachable states. It is shown that the system can be accessible but neither small-time controllable nor controllable in finite time. In particular, if the generators of quantum dynamical semigroups are unital, then the reachable sets admit easy characterizations as they monotonically grow in time. The two level case is treated in detail.
