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…
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…
Opinion: Revisiting synthetic data classifications from a privacy perspective
Vibeke Binz Vallevik, Serena Elizabeth Marshall, Aleksandar Babic +1
Synthetic data is emerging as a cost-effective solution necessary to meet the increasing data demands of AI development, created either from existing knowledge or derived from real…
Testing Medical Rules Web Services in Practice
Christoph Laaber, Shaukat Ali, Thomas Schwitalla +1
The Cancer Registry of Norway (CRN) collects and processes cancer-related data for patients in Norway. For this, it employs a sociotechnical software system that evolves with chang…
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…
Quantum Neural Network Classifier for Cancer Registry System Testing: A Feasibility Study
Xinyi Wang, Shaukat Ali, Paolo Arcaini +2
The Cancer Registry of Norway (CRN) is a part of the Norwegian Institute of Public Health (NIPH) and is tasked with producing statistics on cancer among the Norwegian population. F…
Permissioned Blockchain-based Framework for Ranking Synthetic Data Generators
Narasimha Raghavan Veeraragavan, Mohammad Hossein Tabatabaei, Severin Elvatun +3
Synthetic data generation is increasingly recognized as a crucial solution to address data related challenges such as scarcity, bias, and privacy concerns. As synthetic data prolif…
LLMs in the Heart of Differential Testing: A Case Study on a Medical Rule Engine
Erblin Isaku, Christoph Laaber, Hassan Sartaj +3
The Cancer Registry of Norway (CRN) uses an automated cancer registration support system (CaReSS) to support core cancer registry activities, i.e, data capture, data curation, and…
Can I trust my fake data -- A comprehensive quality assessment framework for synthetic tabular data in healthcare
Vibeke Binz Vallevik, Aleksandar Babic, Serena Elizabeth Marshall +7
Ensuring safe adoption of AI tools in healthcare hinges on access to sufficient data for training, testing and validation. In response to privacy concerns and regulatory requiremen…
