    Enhanced NQS via Annealed Gradient Descent

    Shiwei Zhou, Yiming Huang, Xiao Yuan, Xiaoxia Cai

    quant-ph · cs.LG · physics.chem-ph · physics.comp-ph

    Neural quantum states offer expressive representations of quantum many-body wave functions, yet their practical accuracy can be limited by stochastic optimization rather than representational capacity. Here we identify a finite-sample instability, termed subspace trapping, in which physically important configurations become strongly underestimated, remain absent from successive sampling batches and receive insufficient gradient feedback. This...

    Quantum Reservoir Computing: Recent Advances and Future Directions

    Shehbaz Tariq, Muhammad Talha, Arshid Ali, Muhammad Diyan, Symeon Chatzinotas

    quant-ph · cs.LG

    Quantum reservoir computing (QRC) uses the dynamics of a fixed or weakly tuned quantum system to transform temporal and sequential inputs into measured features, while training is typically confined to a classical readout. This separation reduces reliance on repeated quantum parameter updates and avoids the barren plateaus associated with variational circuit training. Its computational power is often attributed to the exponentially large...
