Dynamical phase transitions in quantum reservoir computing

Rodrigo Martínez-Peña, Gian Luca Giorgi, Johannes Nokkala +2

Closed quantum systems exhibit different dynamical regimes, like Many-Body Localization or thermalization, which determine the mechanisms of spread and processing of information. H…

Information Processing Capacity of Spin-Based Quantum Reservoir Computing Systems

R. Martínez-Peña, J. Nokkala, G. L. Giorgi +2

The dynamical behaviour of complex quantum systems can be harnessed for information processing. With this aim, quantum reservoir computing (QRC) with Ising spin networks was recent…

Gaussian states of continuous-variable quantum systems provide universal and versatile reservoir computing

Johannes Nokkala, Rodrigo Martínez-Peña, Gian Luca Giorgi +3

We establish the potential of continuous-variable Gaussian states of linear dynamical systems for machine learning tasks. Specifically, we consider reservoir computing, an efficien…

Probing the spectral dimension of quantum network geometries

Johannes Nokkala, Jyrki Piilo, Ginestra Bianconi

We consider an environment for an open quantum system described by a "Quantum Network Geometry with Flavor" (QNGF) in which the nodes are coupled quantum oscillators. The geometric…
