论文摘要
我们提出了一种新的方案，用于产生Ramsey干涉法最佳挤压状态。该方案由一系列一轴扭曲的脉冲和旋转组成，两者都可以直接实现实现。最终的状态显示与海森堡极限成正比的计量学增益。我们证明，即使在实施单轴扭曲的脉冲的振幅上以及考虑到由于光子散射引起的现实损失时，也要保持海森堡的缩放。
We propose a novel scheme for the generation of optimal squeezed states for Ramsey interferometry. The scheme consists of an alternating series of one-axis twisting pulses and rotations, both of which are straightforward to implement experimentally. The resulting states show a metrological gain proportional to the Heisenberg limit. We demonstrate that the Heisenberg scaling is maintained even when placing constraints on the amplitude of the pulses implementing the one-axis twisting and when taking into account realistic losses due to photon scattering.
