Session 1

We present a local framework for quantum parameter estimation in linear optical systems, where the unknown parameter is encoded through deformations of an experimentally accessible mode basis. The resulting quantum Fisher information decomposes into two distinct contributions: a coherent contribution, generated by parameter-induced dynamics within the accessible modes and capable of Heisenberg...

Session 1

Quantum-chaotic dynamics in mixed phase space can enhance metrological sensitivity through mechanisms governed by global homoclinic structures. Building on a semiclassical formulation of the quantum Fisher information, we show that global homoclinic manifolds provide a practical guide to the most sensitive initial states. These manifolds organize transport near edge-of-chaos boundaries into...
