摘要:

我们最近提出了一种量子控制方法的基础上的知识的能谱作为一个外部控制参数的函数[物理评论快报。{ \bf 99},036806(2007)]。到目前为止,我们的方法已被应用于连接的基态的目标状态,在所有情况下的能量本征态。在本文中,我们扩展该方法,以获得更一般的目标状态,工作,具体来说,与两个相互作用的电子限制在半导体双量子阱系统。也就是说,我们已经表明,相同的基本方法可以用来获得本地化,纠缠,和一般的叠加系统的本征态。

英文摘要:

We have recently proposed a quantum control method based on the knowledge of the energy spectrum as a function of an external control parameter [Phys. Rev. Lett. {\bf 99}, 036806 (2007)]. So far, our method has been applied to connect the ground state to target states that were in all cases energy eigenstates. In this paper we extend that method in order to obtain more general target states, working, for concreteness, with a system of two interacting electrons confined in semiconductor double quantum wells. Namely, we have shown that the same basic method can be employed to obtain localization, entanglement, and general superpositions of eigenstates of the system.
