A Multiparty Homomorphic Encryption Approach to Confidential Federated Kaplan Meier Survival Analysis
Narasimha Raghavan Veeraragavan, Svetlana Boudko, Jan Franz Nygård
The proliferation of real-world health data enables multi-institutional survival studies, yet privacy constraints preclude centralizing sensitive records. We present a privacy-pres…
Ultrastrong Coupling and Coherent Dynamics in a Gate-Tunable Transmon Qubit
I. Casal Iglesias, F. J. Matute-Cañadas, G. O. Steffensen +10
Ultrastrong light-matter coupling (USC) gives access to exotic quantum phenomena and promises faster quantum gates, yet coherent time-domain control in this regime remains largely…
Anomalous metallic phase and reduced critical current in superconducting nanowires due to inverse proximity effect
G. M. Oliveira, G. O. Steffensen, I. Casal Iglesias +7
Superconductor-to-metal transitions (SMTs) are key probes of mesoscopic superconductivity, but their interpretation can be complicated by device geometry and measurement conditions…
Assessing Quantum Extreme Learning Machines for Software Testing in Practice
Asmar Muqeet, Hassan Sartaj, Aitor Arrieta +6
Machine learning has been extensively applied for classical software testing activities such as test generation, minimization, and prioritization. Along the same lines, there has b…
Federated Survival Analysis with Node-Level Differential Privacy: Private Kaplan-Meier Curves
Narasimha Raghavan Veeraragavan, Jan Franz Nygård
We investigate how to calculate Kaplan-Meier survival curves across multiple health-care jurisdictions while protecting patient privacy with node-level differential privacy. Each s…
Can One Safety Loop Guard Them All? Agentic Guard Rails for Federated Computing
Narasimha Raghavan Veeraragavan, Jan Franz Nygård
We propose Guardian-FC, a novel two-layer framework for privacy preserving federated computing that unifies safety enforcement across diverse privacy preserving mechanisms, includi…
