The paper proposes a quantum federated learning framework that extends parameter-space geometry to mixed states, using the Bures metric as a local preconditioner and the mean Uhlmann curvature to create an aggregation rule that down‑weights unreliable clients. It provides theoretical convergence guarantees and demonstrates through trapped‑ion quantum emulator experiments that the method retains high accuracy under device heterogeneity and outperforms standard federated averaging, which suffers under strong noise.

The paper introduces a hybrid quantum–classical regression framework that uses a lightweight classical embedding as a learnable geometric preconditioner to improve the conditioning of a downstream variational quantum circuit. It further incorporates a curriculum optimization protocol that gradually increases circuit depth and switches from SPSA-based exploration to Adam-based fine‑tuning. Experiments on PDE‑informed and standard regression datasets show that this approach consistently outperforms pure QNN baselines, yielding more stable convergence and reduced structured errors, especially in data‑limited regimes.
