论文摘要
在本文中，我们研究了两路径光学干涉仪与不对称束分裂器的相位敏感性。在这里，我们介绍了透射率和光束分离器的相位的最佳条件，以获得具有平等对称性的一般非古典状态的最高敏感性。此外，我们解决了一个有争议的问题，即该方案与相干性状态和光子添加或光子提取的挤压真空状态的结合是否比使用一致的状态和挤压真空状态的最著名的真空状态更好或更糟。
In this paper, we investigate the phase sensitivities in two-path optical interferometry with asymmetric beam splitters. Here, we present the optimal conditions for the transmission ratio and the phase of the beam splitter to gain the highest sensitivities for a general class of non-classical states with parity symmetry. Additionally, we address the controversial question of whether the scheme with a combination of coherent state and photon-added or photon-subtracted squeezed vacuum state is better or worse than the most celebrated one using a combination of coherent state and squeezed vacuum state.
