Abstract

The precision of optical gyroscope can be improved by enhancing Sagnac effect. Aiming at the accuracy of optical gyroscope restricted by the theoretical limit, shot noise limit, we firstly analyze the theoretical limit of Sagnac effect in optical regime with quantum theory, and point out the physical reasons for the precision limit. And then a quantum entanglement state, Yurke state, with photon number difference measurement is advised to break through shot noise limit for Sagnac effect enhancement. This proposed scheme can achieve the true quantum limit, Heisenberg limit, and offer a new idea for improving the performance of optical sensors based on Sagnac effect.
