Demonstration of RIP gates in a quantum processor with negligible transverse coupling
Muir Kumph, James Raftery, Aaron Finck +8
Here, we report the experimental demonstration of a novel multi-mode linear bus interferometer (LBI) coupler in a six qubit superconducting quantum processor. A key feature of this…
Spectator Errors in Tunable Coupling Architectures
D. M. Zajac, J. Stehlik, D. L. Underwood +9
The addition of tunable couplers to superconducting quantum architectures offers significant advantages for scaling compared to fixed coupling approaches. In principle, tunable cou…
Merged-Element Transmons: Design and Qubit Performance
H. J. Mamin, E. Huang, S. Carnevale +12
We have demonstrated a novel type of superconducting transmon qubit in which a Josephson junction has been engineered to act as its own parallel shunt capacitor. This merged-elemen…
Tunable Coupling Architecture for Fixed-frequency Transmons
J. Stehlik, D. M. Zajac, D. L. Underwood +9
Implementation of high-fidelity two-qubit operations is a key ingredient for scalable quantum error correction. In superconducting qubit architectures tunable buses have been explo…
Demonstration of a High-Fidelity CNOT for Fixed-Frequency Transmons with Engineered ZZ Suppression
A. Kandala, K. X. Wei, S. Srinivasan +6
Improving two-qubit gate performance and suppressing crosstalk are major, but often competing, challenges to achieving scalable quantum computation. In particular, increasing the c…
