Differential Geometry of Quantum States, Observables and Evolution
The geometrical description of Quantum Mechanics is reviewed and proposed as
an alternative picture to the standard ones. The basic notions of observables,
states, evolution and composition of systems are analised from this
perspective, the relevant geometrical structures and their associated algebraic
properties are highlighted, and the Qubit example is thoroughly discussed.Comment: 20 pages, comments are welcome
On the notion of composite system
The notion of composite system made up of distinguishable parties is
investigated in the context of arbitrary convex spaces.Comment: 9 pages. Comments are welcom
Focus point: classical and quantum information geometry
The interplay between Differential Geometry, Mathematical Statistics, Probability Theory and Quantum Mechanics resulting in the so-called field of Classical and Quantum Information Geometry represents one of the most effective examples of cross-fertilizations of modern Science. Roughly speaking, Information Geometry deals with the understanding of the differential geometric properties of suitable manifolds of Classical probability distributions and Quantum states, and with the concrete possible applications that such a theoretical understanding necessarily triggers
