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…
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…
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…
Development of TiN/AlN-based superconducting qubit components
Benedikt Schoof, Moritz Singer, Simon Lang +4
This paper presents the fabrication and characterization of superconducting qubit components from titanium nitride (TiN) and aluminum nitride (AlN) layers to create Josephson junct…
Tantalum thin films sputtered on silicon and on different seed layers: material characterization and coplanar waveguide resonator performance
Moritz Singer, Benedikt Schoof, Harsh Gupta +3
Superconducting qubits are a promising platform for large-scale quantum computing. Besides the Josephson junction, most parts of a superconducting qubit are made of planar, pattern…
