Gatemonium: A Voltage-Tunable Fluxonium
Published 2025-02-01“…The linear inductance is achieved using 600 planar Al-InAs Josephson junctions (JJs) in series. By tuning the single junction with a gate voltage, we demonstrate electrostatic control of the effective Josephson energy, tuning the weight of the fictitious phase particle. …”

Quantum theory of Bloch oscillations in a resistively shunted transmon
Published 2025-02-01“…Abstract A transmon qubit embedded in a high-impedance environment acts in a way dual to a conventional Josephson junction. In analogy to the AC Josephson effect, biasing of the transmon by a direct current leads to the oscillations of voltage across it. …”
