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…
