Summary

Lorenzo Scarpelli from Qilimanjaro Quantum Tech presents their work on fluxonium qubits for analog quantum computation. He explains the theoretical basis: fluxonium circuits can be mapped to spin models, with persistent currents representing spin states. The qubit is operated at the flux degeneracy point, where it is insensitive to flux noise, leading to long coherence times. He discusses the design of their prototype, including a double-loop fluxonium with tunable parameters, and shows experimental results: two-dimensional potential mapping, qubit spectroscopy, and extraction of circuit parameters. He highlights the low transition frequency (below 100 MHz) which reduces sensitivity to electric noise. Challenges include readout of persistent currents, tunable interactions, and scaling up. They are developing a flip-chip architecture and have successfully measured 15 out of 15 qubits in a recent prototype. The talk concludes with a Q&A session addressing flux noise sensitivity and coherence times.
