"significantly reduce overhead realizing fault-tolerance quantum computing... for the same computational task, a higher-fidelity fluxonium quantum computer may need significantly fewer number of qubits... fluxonium-based processors could perform far more powerful computations than transmon-based ones, using the same number of physical qubits. In their next studies, the team would like to scale up their system and try to make it fault-tolerant while retaining a high fidelity"
