论文摘要
我们提出了量子控制方案，用于在自动镇分裂的系统中对目标状态进行高保真制备。我们通过绝热地消除不参与进化的状态来研究从四级系统获得的近似三级系统。在我们的工作中，我们使用线性，arctan和roland-cerf函数在系统的两个特征状态之间转移种群，这些函数在长时间的进化时间内获得了高保真度。此外，为了克服实验设置的寿命所给出的限制，我们提出了一个加速绝热的进化，并具有与绝热协议的快捷方式，这使我们能够达到接近一个但更快的忠诚度。
We propose quantum control protocols for the high-fidelity preparation of target states in systems with Autler-Townes splitting. We investigate an approximated three-level system obtained from a four-level one by adiabatically eliminating a state that does not participate in the evolution. In our work we use linear, arctan, and Roland-Cerf functions for transferring population between two eigenstates of the system obtaining a high fidelity for long evolution times. Additionally, in order to overcome the restriction given by the lifetimes of the experimental setup, we propose an accelerated adiabatic evolution with a shortcut to adiabaticity protocol, which allows us to reach fidelities close to one but much faster.
