Quantifying surface losses in superconducting aluminum microwave resonators
Elizabeth Hedrick, Faranak Bahrami, Alexander C. Pakpour-Tabrizi +11
The recent realization of millisecond-scale coherence with tantalum-on-silicon transmon qubits showed that depositing the Al/AlOx/Al Josephson junction in a high purity, ultrahigh…
2D transmons with lifetimes and coherence times exceeding 1 millisecond
Matthew P. Bland, Faranak Bahrami, Jeronimo G. C. Martinez +14
Materials improvements are a powerful approach to reducing loss and decoherence in superconducting qubits because such improvements can be readily translated to large scale process…
Vortex Motion Induced Losses in Tantalum Resonators
Faranak Bahrami, Matthew P. Bland, Nana Shumiya +17
Tantalum (Ta) based superconducting circuits have been demonstrated to enable record qubit coherence times and quality factors, motivating a careful study of the microscopic origin…
Eliminating Surface Oxides of Superconducting Circuits with Noble Metal Encapsulation
Ray D. Chang, Nana Shumiya, Russell A. McLellan +15
The lifetime of superconducting qubits is limited by dielectric loss, and a major source of dielectric loss is the native oxide present at the surface of the superconducting metal.…
