摘要：
In view of the fact that the quantum inputs usually needs double input / double output, an optical structure of photon entangled fiber optic gyroscope using double circulators is proposed. The operational principle of photon entangled fiber optic gyroscope based on N00N state is described. The quantum interference formula of de Broglie wave for photon entangled fiber optic gyroscope is derived, and the phase detection sensitivity of N00N state is compared with that of classical state and general photon number state with the same photon number (optical power). The analysis shows that N00N state as the maximum optical path entangled state can beat the shot noise limit and reach the Heisenberg limit, while other non-classical states may be difficult to beat the shot noise limit due to the inherent probability of its second order coincidence and high order coincidence of the output state. © 2021, Editorial Department of Journal of Chinese Inertial Technology.
