## Description

- description: We analyzed the computational mechanism of redox-type ion-gating reservoirs
    (Redox-IGRs)—a class of physical reservoir computing (PRC) devices that utilize
    redox dynamics induced by ion gating for information processing—operated with
    physical masking (PM), in which a simple triangular drain voltage dynamically
    modulates the conductance of the device. The periodic drain perturbation enriches
    the temporal diversity of the conductance response, leading to enhanced nonlinear
    dynamics. Information-processing-capacity (IPC) analysis revealed that PM markedly
    increases nonlinear capacity while maintaining linear memory capacity, resulting
    in a total IPC increase from 11 to 20. This doubling of IPC indicates an expansion
    of the reservoir’s effective dimensionality and explains the improved performance
    observed in nonlinear dynamical system prediction tasks. These findings demonstrate
    that PM effectively enhances the expressive power of Redox-IGRs and provides a
    simple, general strategy for boosting the high-dimensional dynamics of PRC systems.
