- 摘要:
- 提出了一个利用Lyapunov控制方法在4×4光晶格内实现分数量子态的理论方案.通过优化控制场,使保真度达到一个较高的稳定值,并且控制场对系统所产生的不确定度具有鲁棒性.该控制方案可以推广到n×n光晶格系统中,并且可为研究多体系统中的强相互作用提供依据.
- Abstract:
- We propose a theoretical scheme to prepare the fractional quantum state by Lyapunov control in 4×4 optical lattice in this paper. The fidelity can achieve a high stable value by optimizing the control fields, and it is insensitive to the influence of uncertainties for control fields. Our scheme can be generalized to n×n lattice, which provides a powerful criterion for researching the strong interaction in multi-body systems.
