Berry's phase in view of quantum estimation theory, and its intrinsic relation with the complex structure

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/88929In this paper, it is pointed out that the Berry's phase is a good index of degree of no-commutativity of the quantum statistical model. Intrinsic relations between the `complex structure' of the Hilbert space and Berry's phase is also discussed.Quantum PhysicsBerry's phase in view of quantum estimation theory, and its intrinsic relation with the complex structuretext
