ArXiv

Analysis

This paper addresses a critical problem in quantum metrology: the degradation of phase estimation accuracy due to phase-diffusive noise. It demonstrates a practical solution by jointly estimating phase and phase diffusion using deterministic Bell measurements. The use of collective measurements and a linear optical network highlights a promising approach to overcome limitations in single-copy measurements and achieve improved precision. This work contributes to the advancement of quantum metrology by providing a new framework and experimental validation of a collective measurement strategy.
Reference
