Beyond the Edge of Chaos: Stability-Expressivity Transfer in Reservoir Forecasting

By analyzing the collective dynamics of the teacher-forced reservoir, this work finds that the target dynamics are represented mainly by stable Lyapunov modes whose finite-time stability is strongly modulated by the input, which motivates a stability-expressivity transfer index, which accurately identifies the optimal...

Evolution-Level Quantum Optimal Control of Single-Qubit Gates with Physics-Informed Neural Networks

This work uses physics-informed neural networks to represent single-qubit gate design at this evolution level: the control fields, the Bloch-state trajectories, and the total duration are learned together under the Bloch equation.
