Fault-tolerant Fusion-based Quantum Computing with the Four-legged Cat Code
Harshvardhan K. Babla, James D. Teoh, Jahan Claes +4
The four-legged cat code is a quantum error-correcting code designed to address the predominant error in bosonic modes: single-photon loss. It was the first such code to surpass th…

Impact of Josephson junction array modes on fluxonium readout
Shraddha Singh, Gil Refael, Aashish Clerk +1
Dispersive readout of superconducting qubits is often limited by readout-drive-induced transitions between qubit levels. While there is a growing understanding of such effects in t…
