Overcoming Fourier Locking in Quantum Data Re-uploading Classifiers via Spectral Homotopy
Spencer Topel
Data re-uploading parameterized quantum circuits (DRU-PQCs) are universal function approximators, yet their expressivity produces oscillatory, non-convex loss landscapes that resis…

Rendering Coherent Scattering via Quantum Collision Models
João S. Ferreira, Spencer S. Topel, Pierre Fromholz +1
Traditional light rendering techniques treat the optical properties of materials as static, yet this assumption breaks down in cases where these properties dynamically evolve in re…
