Quantum Barankin bounds beyond local unbiasedness: Analytic results for Gaussian states via a right-division framework
Maximilian Reichert, Javier Navarro, Gerardo Adesso +2
We propose a quantum version of the Barankin bound as an alternative to the quantum Cramér-Rao bound for quantum parameter estimation. The quantum Barankin bound provides a lower b…

Resource-optimal quantum mode parameter estimation with multimode Gaussian states
Maximilian Reichert, Mikel Sanz, Nicolas Fabre
Quantum mode parameter estimation determines parameters governing the shape of electromagnetic modes occupied by a quantum state of radiation. Canonical examples, time delays and f…
