量子控制景观

Quantum Control Landscapes

Raj Chakrabarti, Herschel Rabitz

摘要:

大量的实验、数值和分析证据表明,找到将量子动力学系统转向所需目标的最佳控制是非常容易的。这使得复杂量子系统的控制成为可能,尽管在模拟中求解薛定谔方程的费用很高,而且在实验室中环境退相干的影响也很复杂。最近的工作表明,这种简单性起源于量子控制问题的解决方案集的普遍性质,这些问题与经典问题有着根本的不同。在这里,我们回顾了旨在系统地表征这些特性的研究,从而实现量子控制机制的分类和全局有效的量子控制算法的设计。

英文摘要:

Numerous lines of experimental, numerical and analytical evidence indicate that it is surprisingly easy to locate optimal controls steering quantum dynamical systems to desired objectives. This has enabled the control of complex quantum systems despite the expense of solving the Schrodinger equation in simulations and the complicating effects of environmental decoherence in the laboratory. Recent work indicates that this simplicity originates in universal properties of the solution sets to quantum control problems that are fundamentally different from their classical counterparts. Here, we review studies that aim to systematically characterize these properties, enabling the classification of quantum control mechanisms and the design of globally efficient quantum control algorithms.
