Abstract. We study a system composed of a free quantum particle trapped in a box whose walls can change their position. We prove the global approximate controllability of the system: any initial pure state can be driven arbitrarily close to any target pure state in the Hilbert space of the free particle with a predetermined final position of the box. To this purpose we consider weak solutions of the Schrödinger equation and use a stability theorem for the time-dependent Schrödinger equation.

移动壁对盒子中量子粒子的全局近似可控性

摘要。我们研究了一个由被困在盒子里的自由量子粒子组成的系统,盒子的墙壁可以改变它们的位置。我们证明了系统的全局近似可控性:在具有预定的盒子最终位置的自由粒子的希尔伯特空间中,任何初始纯态都可以被任意驱动到接近任何目标纯态。为此,我们考虑薛定谔方程的弱解,并对瞬态薛定谔方程使用稳定性定理。
