论文摘要
我们提出了一条一般的协议，以控制基于最小化绝热作用的封闭量子系统。使用基于量子发展的几何形状的工具通过量子绝热的腕足激素，我们表明可以实现对临界量子系统基态的高忠诚度控制，并且仅需要对基态光谱间隙进行合理的近似值。我们为三个广泛适用的系统展示了我们的结果：Landau-Zener，Ising和完全连接的自旋模型。
We present a general protocol to control closed quantum systems that is based on minimising the adiabatic action. Using tools based on the geometry of quantum evolutions through the quantum adiabatic brachistochrone, we show that high fidelity control of the ground state of critical quantum systems can be achieved and requires only a reasonable approximation for the ground state spectral gap. We demonstrate our results for three widely applicable systems: the Landau-Zener, Ising, and fully connected spin models.
