Optimal multiple-phase estimation with multi-mode NOON states against photon loss

Min Namkung, Dong-Hyun Kim, Seongjin Hong +3

Multi-mode NOON states can quantum-enhance multiple-phase estimation in the absence of photon loss. However, a multi-mode NOON state is known to be vulnerable to photon loss, and i…
