Let $\mathcal{E}^{\bar{n}_{\rm B},\eta_s}$ be the channel with background noise $\bar{n}_{\rm B}$ and transmittance $\eta_s$. For two-mode Gaussian input states with a fixed photon…

Consider a sensing network of $K$ sensors containing $N$ atoms, with the atoms distributed among the sensors, and suppose the target is a linear function of the sensor fields…

Consider the two multiparameter estimation problems studied in the paper, and compare generalized NOON states (GNSs) with states that are separable across modes. Mode-separable per…

Let $\boldsymbol{v}$ be a vector whose components are rationally proportioned, let $\theta_1=\boldsymbol{v}^T\boldsymbol{\phi}$, and let $\mathcal{S}(N_{\max})$ be the subspace wit…
