论文摘要
我们建议如何设计纵向耦合，以加速纵向耦合的量子轴的测量，这是以捷径为绝热性的概念激励的。不同的调制量是从两种反向工程和脱糖驾驶方法呈负设计的，用于在纳米级尺度上实现较大的信噪比值（SNR）的值。相比之下，我们证明我们的协议的表现优于指针状态分离和SNR的通常的周期调制。最后，考虑到最先进的电路量子电动力学体系结构，我们显示了可能的实现，估计了测量过程允许的最小时间。
We propose how to engineer the longitudinal coupling to accelerate the measurement of a qubit longitudinally coupled to a cavity, motivated by the concept of shortcuts to adiabaticity. Different modulations are inversely designed from two methods of inverse engineering and counter-diabatic driving, for achieving larger values of the signal-to-noise ratio (SNR) at nanosecond scale. By comparison, we demonstrate that our protocols outperform the usual periodic modulations on the pointer state separation and SNR. Finally, we show a possible implementation considering state-of-the-art circuit quantum electrodynamics architecture, estimating the minimal time allowed for the measurement process.
