Quantum Krylov Learning

The Hamiltonian of a natural quantum system is usually determined indirectly, by proposing microscopic models and comparing their predicted observables with experiment. A more direct approach is to extract information about the Hamiltonian from measurements on the system itself. In many settings, however, direct access...

Krylov Break Times from an Inhomogeneous Lieb--Robinson Light Cone

Krylov and Lanczos approximations are used in quantum dynamics, quantum subspace methods, and Hamiltonian learning. A practical question is how long an $m$-dimensional Krylov truncation can be trusted. We argue that this time is fixed by causal propagation on the associated Jacobi chain. The relevant distance is not th...

Discretization-Aware Fine-Tuning for Quantum Machine Learning with Chemical Foundation Models

This work introduces discretization-aware fine-tuning (DAFT), a method that adapts a pre-trained chemical foundation model to produce representations that remain informative after quantization, and evaluates both quantum and classical models under a controlled setting in which they receive identical discretized bit-str...
