Mechanistic Interpretability and Causal Feature Steering of Neural Quantum States via Sparse Autoencoders
Neural Quantum States (NQS) are a remarkably expressive class of variational ansätze for quantum many-body wavefunctions, yet little is understood about their internal mechanisms: trained on variational objectives alone, how do NQS accurately capture physical observables that the…
