RT Journal Article T1 Nonlinear fiber gyroscope for quantum metrology A1 Luis Aina, Alfredo A1 Morales, Irene A1 Rivas Vargas, Ángel AB We examine the performance of a nonlinear fiber gyroscope for improved signal detection beating the quantum limits of its linear counterparts. The performance is examined when the nonlinear gyroscope is illuminated by practical field states, such as coherent and quadrature squeezed states. This is compared with the case of more ideal probes such as photon-number states.
