Superconducting Qubit Gates Robust to Parameter Fluctuations
Emily Wright, Leo Van Damme, Niklas J. Glaser +14
State-of-the-art single-qubit gates on superconducting transmon qubits can achieve the fidelities required for error-corrected computations. However, parameter fluctuations due to…

Scalable Fluxonium-Transmon Architecture for Error Corrected Quantum Processors
Lukas Heunisch, Longxiang Huang, Stephan Tasler +8
We propose a hybrid quantum computing architecture composed of alternating fluxonium and transmon qubits, that are coupled via transmon tunable couplers. We show that this system o…

Sensitivity-Adapted Closed-Loop Optimization for High-Fidelity Controlled-Z Gates in Superconducting Qubits
Niklas J. Glaser, Federico A. Roy, Ivan Tsitsilin +13
Achieving fast and high-fidelity qubit operations is crucial for unlocking the potential of quantum computers. In particular, reaching low gate errors in two-qubit gates has been a…
