Substrate-metal interface engineering enhances TaN/Ta thin film superconducting resonator performance
Moritz Singer, Harsh Gupta, Benedikt Schoof +6
Tantalum has been demonstrated as a promising material for superconducting qubits. However, comparatively little attention has been given to its nitrides. Tantalum nitride exhibits…
Optimizing CMOS-compatible, superconducting titanium nitride resonators: Deposition conditions and structuring processes
Simon J. K. Lang, Alexandra Schewski, Ignaz Eisele +10
The paper investigates how deposition conditions, etching power, and resist‑strip temperature influence the performance of superconducting titanium nitride coplanar waveguide reson…
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…
Interfacial Strain and Structural Defects Govern the Performance of Tantalum Superconducting Waveguide Resonators
Moritz Singer, Harsh Gupta, Benedikt Schoof +3
Tantalum (Ta) is a promising material for reaching long coherence times in superconducting qubits. A detailed understanding of the underlying structure-property relationship remain…
Enhanced Tantalum Superconducting Resonator Performance via All-Surface Organic Monolayer Passivation
Harsh Gupta, Moritz Singer, Benedikt Schoof +4
Tantalum is a promising platform for superconducting quantum circuits, yet coherence times remain limited by dielectric losses from interfacial two-level systems (TLS), exacerbated…
High temporal stability of niobium superconducting resonators by surface passivation with organophosphonate self-assembled monolayers
Harsh Gupta, Rui Pereira, Leon Koch +6
One main limiting factor towards achieving high coherence times in superconducting circuits is two level system (TLS) losses. Mitigating such losses requires controlling the format…
