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…
A simple all-microwave entangling gate for fixed-frequency superconducting qubits
Jerry M. Chow, A. D. Corcoles, Jay M. Gambetta +8
We demonstrate an all-microwave two-qubit gate on superconducting qubits which are fixed in frequency at optimal bias points. The gate requires no additional subcircuitry and is tu…
