Bayesian quantum phase estimation with fixed photon states

Boyu Zhou, Saikat Guha, Christos N. Gagatsos

We consider a two-mode bosonic state with fixed photon number $n\in \mathbb{N}$, whose upper and lower modes pick up a phase $\ddot{I}•$ and $-\ddot{I}•$ respectively. We compute the optimal Fo…
