Phase qubits fabricated with trilayer junctions
M. Weides, R. C. Bialczak, M. Lenander +11
We have developed a novel Josephson junction geometry with minimal volume of lossy isolation dielectric, being suitable for higher quality trilayer junctions implemented in qubits.…

Dynamical decoupling and noise spectroscopy with a superconducting flux qubit
Jonas Bylander, Simon Gustavsson, Fei Yan +7
The characterization and mitigation of decoherence in natural and artificial two-level systems (qubits) is fundamental to quantum information science and its applications. Decohere…

Energy decay and frequency shift of a superconducting qubit from non-equilibrium quasiparticles
M. Lenander, H. Wang, Radoslaw C. Bialczak +12
Quasiparticles are an important decoherence mechanism in superconducting qubits, and can be described with a complex admittance that is a generalization of the Mattis-Bardeen theor…
