Single-mode squeezed-state conjecture for optimal lossy multimode probes
Consider a lossy multimode passive bosonic channel and let the probe be a quantum state prepared in a single spatial mode belonging to the linear span of the modes on which the cha…

Optimal Gaussian probe conjecture for beam-displacement sensing
A single spatial mode is excited in a Gaussian state, with the state potentially displaced and squeezed. Optimal Gaussian probe conjecture. The optimum Gaussian-state probe is a si…
