Persistent quantum advantage in simultaneous estimation of multiple phases using entangled photons
We propose a robust multiple-phase estimation scheme using optimized multi-mode entangled photons, achieving persistent quantum enhancement across all photon loss regimes. It outperforms classical benchmarks and conventional NOON states, offering practical and loss-robust quantum sensing.
