论文摘要
我们应用量子最佳对照来塑造一维光学晶格中玻色 - 因斯坦冷凝水的相位分布。通过根据最佳控制理论确定的晶格位置的时间依赖性调制，我们在每个晶格位点的相空间中准备，翻译和挤压的高斯州以及高斯州的叠加。这些非平凡状态的完全重建是通过最大似然状态断层扫描进行的。作为我们方法在量子模拟中的实际应用，我们初始化了最佳的浮质状态叠加中的原子波函数，以增强动态隧道信号。
We apply quantum optimal control to shape the phase-space distribution of Bose-Einstein condensates in a one-dimensional optical lattice. By a time-dependent modulation of the lattice position, determined from optimal control theory, we prepare, in the phase space of each lattice site, translated and squeezed Gaussian states, and superpositions of Gaussian states. Complete reconstruction of these non-trivial states is performed through a maximum likelihood state tomography. As a practical application of our method to quantum simulations, we initialize the atomic wavefunction in an optimal Floquet-state superposition to enhance dynamical tunneling signals.
