论文摘要
以快速准确的方式操纵接受非高斯动态的量子系统正成为许多量子应用的基础。在这里，我们专注于经典和量子方案，这些方案将状态传递到双孔电位上。经典协议是通过变形电势而实现的，而量子的协议则是通过反诱惑驾驶的辅助。我们表明，量子协议的性能更快，准确。最后，我们为传输方案的性能（即协议分级）设计了一个功绩，该图形仅取决于基本的物理量，并且说明了该过程的量子速度限制，保真度和过程的热力学。我们使用经典和量子协议测试协议分级，并表明量子协议比经典方案更高。
Manipulating quantum systems undergoing non-Gaussian dynamics in a fast and accurate manner is becoming fundamental to many quantum applications. Here, we focus on classical and quantum protocols transferring a state across a double-well potential. The classical protocols are achieved by deforming the potential, while the quantum ones are assisted by a counter-diabatic driving. We show that quantum protocols perform more quickly and accurately. Finally, we design a figure of merit for the performance of the transfer protocols -- namely, the protocol grading -- that depends only on fundamental physical quantities, and which accounts for the quantum speed limit, the fidelity and the thermodynamic of the process. We test the protocol grading with classical and quantum protocols, and show that quantum protocols have higher protocol grading than the classical ones.
