摘要:

我们利用光滑态依赖力实现了快于绝热的双量子比特相位门。力被设计为不留下最终的运动激励,独立于谐波、小振荡极限中的初始运动状态。它们是简单的,明确的时间函数和所需的逻辑相位的门,是基于二次不变量的运动和刘易斯-Riesenfeld阶段的正常模式。

英文摘要:

We implement faster-than-adiabatic two-qubit phase gates using smooth state-dependent forces. The forces are designed to leave no final motional excitation, independently of the initial motional state in the harmonic, small-oscillations limit. They are simple, explicit functions of time and the desired logical phase of the gate, and are based on quadratic invariants of motion and Lewis-Riesenfeld phases of the normal modes.
