<span class="lead-in">Our research program</span> builds falsification frameworks for frontier models and AI alignment claims, with particular focus on local
recoverability assumptions in neural network editing. We combine quantum machine learning methods with classical
testbeds to probe function–representation decoupling, continuation interests, and the reliability of geometric
proxies in model repair.

Current work spans quantum kernel methods for satellite anomaly detection, binarized quantum neural networks,
Hamiltonian dynamics for data augmentation, satellite quantum key distribution, superconducting qubit simulation,
and reproducible superconducting-hardware benchmarks for inter-branch communication witnesses—each
project packaged as a reproducible evaluation harness with diagnostic plots, baselines, and reviewable artifacts
designed to test specific technical claims under controlled experimental conditions.

Research claims are anchored in publishable units: falsifiable hypotheses, experimental protocols, and
measurable outcomes.
