Quantum-Enhanced Optical Phase Estimation via Stochastic Optimization

Year: 2026

Type: conference-paper

Abstract: We propose a self-guided quantum phase estimation protocol based on a squeezed vacuum state and a stochastic optimization algorithm. Our protocol dynamically aligns the measurement basis with the target phase, eliminating the need for prior knowledge of the squeezing parameter. We demonstrate that this approach successfully tracks the target phase across the entire [0, π) periodicity interval, achieving a measurement precision that surpasses the Standard Quantum Limit and approaches the Heisenberg Limit.
