Theory of the Edge-of-Chaos Advantage in Quantum Reservoir Computing

Numerical studies suggest that quantum reservoir computing performs optimally near the edge of chaos, a behavior commonly attributed to a balance between memory retention and nonlinear information processing. Here we develop an explicit quantum reservoir model and rigorously analyze its chaotic regime and integrable po...

Quantum magic and non-commutativity as computational resources in quantum reservoir computing

A theoretical framework in Pauli-Liouville space is developed that provides a unified analytical treatment of the echo state property (ESP), nonlinear expressive power, and quantum resources and shows that the ESP is natively guaranteed by the Liouvillian spectral gap, decoupling it from quantum magic.
