Evidence for a low-gap component in compressively stressed niobium thin films
J. T. Paustian, Maciej Olszewski, Kiichi Okubo +6
We investigate the microwave response of sputtered Nb films as a function of biaxial film stress. Although transport measurements show nearly identical superconducting transition t…
Fabrication-free assessment of microwave losses in germanium-based dielectrics and superconductors
Haoran Lu, Kushagra Aggarwal, Xiangqin Wang +10
We present a flip-chip-based sensing scheme to measure effective microwave losses associated with target materials for quantum technologies, without requiring any device fabricatio…
Resist-free shadow deposition using silicon trenches for Josephson junctions in superconducting qubits
Tathagata Banerjee, Stephen Daniel Funni, Saswata Roy +2
Superconducting qubit fabrication innovations continue to be explored to achieve higher performance. Despite improvements to base layer fabrication and processing, resist-based Jos…
Krypton-sputtered tantalum films for scalable high-performance quantum devices
Maciej W. Olszewski, Lingda Kong, Simon Reinhardt +9
Superconducting qubits based on tantalum (Ta) thin films have demonstrated the highest-performing microwave resonators and qubits. This makes Ta an attractive material for supercon…
