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…
Quantum crosstalk cancellation for fast entangling gates and improved multi-qubit performance
K. X. Wei, E. Magesan, I. Lauer +14
Quantum computers built with superconducting artificial atoms already stretch the limits of their classical counterparts. While the lowest energy states of these artificial atoms s…
Suppressed crosstalk between two-junction superconducting qubits with mode-selective exchange coupling
A. D. K. Finck, S. Carnevale, D. Klaus +8
Fixed-frequency qubits can suffer from always-on interactions that inhibit independent control. Here, we address this issue by experimentally demonstrating a superconducting archit…
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…
