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...
A hardware-efficient, shuttling-free architecture that achieves all-to-all connectivity and develops a hardware-aware scheduling scheme that exploits the native cat--atom $\mathrm{CZ}^{n}$ gate to construct a syndrome-extraction circuit with minimum depth.

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.
