First-order sideband transitions with flux-driven asymmetric transmon qubits
J. D. Strand, Matthew Ware, Félix Beaudoin +4
We demonstrate rapid, first-order sideband transitions between a superconducting resonator and a frequency-modulated transmon qubit. The qubit contains a substantial asymmetry betw…
Coherence in a transmon qubit with epitaxial tunnel junctions
Martin P. Weides, Jeffrey S. Kline, Michael R. Vissers +5
We developed transmon qubits based on epitaxial tunnel junctions and interdigitated capacitors. This multileveled qubit, patterned by use of all-optical lithography, is a step towa…
Sub-micrometer epitaxial Josephson junctions for quantum circuits
Jeffrey S. Kline, Michael R. Vissers, Fabio C. S. da Silva +11
We present a fabrication scheme and testing results for epitaxial sub-micrometer Josephson junctions. The junctions are made using a high-temperature (1170 K) "via process" yieldin…
