Scalable Fluxonium-Transmon Architecture for Error Corrected Quantum Processors
The work proposes a hybrid quantum architecture alternating fluxonium and transmon qubits coupled by tunable couplers to improve scalability for error-corrected processors. This design addresses scaling challenges like level crowding and capacitive loading by using high-coherence fluxoniums as data qubits and transmons as ancillas, while suppressing crosstalk through the alternating arrangement.
