Quantum-Enhanced Fiber-Optic Gyroscopes using Quadrature Squeezing and Continuous-Variable Entanglement

For fiber-optic gyroscope designs, we analyze the quantum enhancement from quadrature-squeezed and entangled optical probe states for rotation sensing. Under realistic experimental constraints and fiber loss, we analytically show substantial variance suppression over classical sensors.
