Fidelity serves as a benchmark for the reliability in quantum information processes, and has
recently attracted much interest as a measure of the susceptibility of dynamics to …

An adaptive denoising algorithm based on local sparse representation (local SR) is
proposed. The basic idea is applying SR locally to clusters of signals embedded in a high …

We study the time evolution of the quantum-classical correspondence (QCC) for the well-
known model of quantized perturbed cat maps on the torus in the very specific regime of …

A spatially extended two-dimensional billiard system named serpent billiard is studied in
quantum and classical picture. It is composed of bends and straight wave-guide segments …

El problema de la correspondencia cuántico-clásica es fundamental para entender la
emergencia del mundo clásico a partir de sistemas regidos por la mecánica cuántica. La …
