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…

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…
