Benchmarking gates in a qubit-bus-qubit tunable transmon architecture
ORAL
Abstract
Using a newly developed frequency tunable transmon qubit (``Xmon''), we are beginning to construct the fundamental gates and architecture for a quantum computer. We show experimental data for gates in a qubit-bus-qubit configuration. We quantify the fidelity of a set of single qubit gates with both randomized benchmarking and tomography. We also investigate the fast swap style cPhase gate [Strauch PRL 2003], where the control qubit is swapped into the bus and interacts dispersively with the target qubit, as a fundamental two-qubit interaction.
