Surface Optimization of Superconducting Aluminum Resonators for Robust Quantum Device Fabrication
Simon J. K. Lang, Ignaz Eisele, Alwin Maiwald +8
The paper studies surface treatment methods for aluminum superconducting resonators to maintain low dielectric loss after a 24‑hour ambient exposure, finding that selective oxide r…
Stability studies on subtractively-fabricated CMOS-compatible superconducting transmon qubits
Chawki Dhieb, Johannes Weber, Samuel Taubenberger +12
Developing fault-tolerant quantum processors with error correction demands large arrays of physical qubits whose key performance metrics (coherence times, control fidelities) must…
Nanoscale Confinement Enhances Ultrafast Demagnetization
Yoav William Windsor, Tobias Lojewski, Moumita Kundu +22
Nanoscale miniaturization has revolutionized the field of spintronics by enabling exponential growth in areal bit density. A similar leap is also expected in device speeds through…
Wafer-Scale Characterization of Al/AlxOy/Al Josephson Junctions at Room Temperature
Simon J. K. Lang, Ignaz Eisele, Johannes Weber +13
Josephson junctions (JJs) are the key element of many devices operating at cryogenic temperatures. Development of time-efficient wafer-scale JJ characterization for process optimiz…
