Quantum reservoir complexity by Krylov evolution approach
Laia Domingo, F. Borondo, Gastón Scialchi +3
Quantum reservoir computing algorithms recently emerged as a standout approach in the development of successful methods for the NISQ era, because of its superb performance and comp…
Integrability to chaos transition through Krylov approach for state evolution
Gastón F. Scialchi, Augusto J. Roncaglia, Diego A. Wisniacki
The complexity of quantum evolutions can be understood by examining their dispersion in a chosen basis. Recent research has stressed the fact that the Krylov basis is particularly…
Classical approach to equilibrium of out-of-time ordered correlators in mixed systems
Tomás Notenson, Ignacio García-Mata, Augusto J. Roncaglia +1
The out-of-time ordered correlator (OTOC) is a measure of scrambling of quantum information. Scrambling is intuitively considered to be a significant feature of chaotic systems and…
Comment on "Exploring chaos in the Dicke model using ground-state fidelity and the Loschmidt echo"
I. García-Mata, A. J. Roncaglia, D. A. Wisniacki
In [PRE \textbf{90}, 022920 (2014), arXiv:1404.6738] a study of the ground state fidelity of the Dicke model as a function of the coupling parameter is presented. Abrupt jumps of t…
Work measurement as a generalized quantum measurement
Augusto J. Roncaglia, Federico Cerisola, Juan Pablo Paz
We present a new method to measure the work performed on a driven quantum system and to sample its probability distribution . The method is based on a simple fact that re…
Relaxation of isolated quantum systems beyond chaos
Ignacio García-Mata, Augusto J. Roncaglia, Diego A. Wisniacki
In classical statistical mechanics there is a clear correlation between relaxation to equilibrium and chaos. In contrast, for isolated quantum systems this relation is -- to say th…
