Edge of Many-Body Quantum Chaos in Quantum Reservoir Computing

Author(s): Kaito Kobayashi and Yukitoshi Motome Reservoir computing (RC) is a machine learning paradigm that harnesses dynamical systems as computational resources. In its quantum extension—quantum reservoir computing (QRC)—these principles are applied to quantum systems, whose rich dynamics broadens the landscape of information processing. In cl… [Phys. Rev.
