Optimal-speed unitary quantum time evolutions and propagation of light with maximal degree of coherence
Carlo Cafaro, Shannon Ray, Paul M. Alsing
It is recognized that Grover arrived at his original quantum search algorithm inspired by his comprehension of the interference of classical waves originating from an array of ante…
Canonical Quantum Coarse-Graining and Surfaces of Ignorance
Shannon Ray, Paul M. Alsing, Carlo Cafaro +1
In this paper we introduce a canonical quantum coarse-graining and use negentropy to connect ignorance as measured by quantum information entropy and ignorance related to quantum c…
Complexity and efficiency of minimum entropy production probability paths from quantum dynamical evolutions
Carlo Cafaro, Shannon Ray, Paul M. Alsing
We present an information geometric characterization of quantum driving schemes specified by su(2;C) time-dependent Hamiltonians in terms of both complexity and efficiency concepts…
Minimum time for the evolution to a nonorthogonal quantum state and upper bound of the geometric efficiency of quantum evolutions
Carlo Cafaro, Paul M. Alsing
We present a simple proof of the minimum time for the quantum evolution between two arbitrary states. This proof is performed in the absence of any geometrical arguments. Then, bei…
Information geometry for Fermi-Dirac and Bose-Einstein quantum statistics
Pedro Pessoa, Carlo Cafaro
Information geometry is an emergent branch of probability theory that consists of assigning a Riemannian differential geometry structure to the space of probability distributions.…
