Non-Gaussian receiver conjecture for QFI saturation in beam-displacement sensing
Consider estimation of a small transverse displacement using an optimal single-mode Gaussian state, and let the quantum Fisher information (QFI) quantify the attainable information…

Proportionality conjecture for the negativity volume of multimode photon-added and photon-subtracted states
Let $V$ be the covariance matrix and let $A^{\pm}_{\rm mix}$ denote the matrix appearing in the condition for Wigner-function negativity. The negativity volume is the integral of t…
