Investigation of Parasitic Two-Level Systems in Merged-Element Transmon Qubits
Etienne Daum, Benedikt Berlitz, Steffen Deck +2
In conventional transmon qubits, decoherence is dominated by a large number of parasitic two-level systems (TLS) residing at the edges of its large area coplanar shunt capacitor an…

Parasitic RF-SQUIDs in superconducting qubits due to wirebonds
B. Berlitz, E. Daum, S. Deck +2
Superconducting qubits show great promise to realize practical quantum computers from micro-fabricated integrated circuits. However, their solid-state architecture bears the burden…
