Probing Coordination Environments in Buried Oxides of Aluminum Josephson Junctions by Resonant X-ray Reflectivity
Paul Corbae, Alex Abelson, Shivani Srivastava +16
Decoherence remains a critical obstacle to achieving high-fidelity, scalable superconducting qubits, with the tunnel barrier of Josephson junctions a key source of loss. Here we ap…

Superconducting qubit decoherence correlated with detected radiation events
A. R. Castelli, K. M. Beck, L. D. H. Alegria +6
Most quantum error correction (QEC) protocols for superconducting qubits assume spatially and temporally uncorrelated decoherence events; however, recent evidence suggests that cos…

Growth and Structure of alpha-Ta films for Quantum Circuit Integration
Loren D. Alegria, Alex Abelson, Eunjeong Kim +5
Tantalum films incorporated into superconducting circuits have exhibited low surface losses, resulting in long-lived qubit states. Remaining loss pathways originate in microscopic…
