A Super-Stable Optical Interferometer with Multi-Pass and its Simple Application
In this paper, we design a super-stable optical interferometer with multi-pass. By using single photon to estimate an unknown phase, our scheme enables considerable high precision and it can beat the standard quantum limit.
