    Quantum Reservoir Computing with Physics-Informed Correction for Reduced-Order PDE Forecasting

    Krishna Bhatia, Harsh, Shalini Devendrababu

    quant-ph · cs.LG

    We study a hybrid proposal--correction architecture for reduced-order PDE forecasting in which a pure-state quantum reservoir computer (QRC) predicts latent coefficient dynamics and a PINN-based physics-informed corrector (PIC) refines local rollout windows. The method is evaluated on Burgers and Kuramoto--Sivashinsky (KS), with KS as the primary chaotic benchmark. On KS, QRC+PIC consistently improves over QRC alone in RMSE, NRMSE, and PDE...

    Partial-Moment PINNs for Caldeira--Leggett Parameter Learning in Quantum Brownian Motion

    Krishna Bhatia

    quant-ph · cs.LG

    We study parameter recovery in the Caldeira--Leggett (quantum Brownian) oscillator from partial moment traces. Our model is a moment-level PINN that predicts the five first/second moments and enforces the linear CL/HPZ ODEs by automatic differentiation. Physical structure is imposed through a PSD (Cholesky) covariance head, high-temperature CL assumptions with $D_{xp}\approx0$, and fluctuation--dissipation ties between $D_{pp}$ and $γ$. On...
