Probing hundreds of individual quantum defects in polycrystalline and amorphous alumina
Chih-Chiao Hung, Liuqi Yu, Neda Foroozani +3
Quantum two-level systems (TLSs) are present in the materials of qubits and are considered defects because they limit qubit coherence. For superconducting qubits, the quintessentia…

Correlating the nanostructure of Al-oxide with deposition conditions and dielectric contributions of two-level systems in perspective of superconducting quantum circuits
S. Fritz, A. Seiler, L. Radtke +4
This work is concerned with Al/Al-oxide(AlO)/Al-layer systems which are important for Josephson-junction-based superconducting devices such as quantum bits. The device perfor…
