Der volle Inhalt der QuelleRadio-frequency fluxonium superconducting circuit for AC-charge sensing applicationsSuperconducting-circuits are artificial quantum systems whose properties can be engineered to match the requirements of each specific application. A typical superconducting circuit is engineered to have a sufficiently an-harmonic transition to be used as a qubit, which can be easily manipulated and read-out thanks to its strong (dipolar) interaction with electromagnetic fields. The property of having a strong dipole moment is particularly interesting for interfacing a superconducting circuit with other quantum systems. For instance, fluorescence from individual electronic spins was successfully detected using a superconducting qubit-based microwave-photon detector operating in the 5-10 GHz band. In the realm of circuit quantum acousto-dynamics (cQAD), the coupling between a qubit and a piezoelectric resonator is used to detect and manipulate the phononic state, typically within the 2-10 GHz range. However, adapting these sensing schemes to lower frequencies, below the conventional operating frequency of superconducting qubits, introduces distinct challenges. First, superconducting qubits are read out thanks to the dispersive shift imparted to a nearby superconducting resonator. As the dispersive shift quickly drops for a cavity detuning exceeding the qubit anharmonicity, weakly anharmonic qubits, such as transmons, require nearly resonant resonators with dimensions scaling inversely with the frequency (as an illustration, a 1 MHz λ/2-coplanar cavity requires a 100-m-long waveguide). Second, low-frequency systems are coupled to a hot thermal bath with which they exchange photons randomly, quickly turning pure quantum states into statistical mixtures. The fluxonium qubit, composed of a Josephson junction shunted simultaneously by a large inductance and a capacitance, presents unique opportunities in the realm of low-frequency superconducting qubits.In this work, we demonstrate a heavy fluxonium with an unprecedentedly low transition frequency of 1.8 MHz, while maintaining the ability to manipulate and read out the qubit using standard microwave techniques. This is made possible by the highly non-linear energy spectrum of the fluxonium, where the first transition occurs in the MHz range while transitions to higher excited states are within the 3-10 GHz range. We successfully demonstrate resolved sideband cooling of the fluxonium, reducing its effective temperature to 23 μK and achieving a ground state population of 97.7%. Our experiments further reveal the qubit's coherent manipulation capabilities, with coherence times of T1=34 μs and T2*=39 μs, along with reliable single-shot state readout.We furthermore demonstrate the qubit's enhanced sensitivity to radio-frequency fields, achieved through direct interaction with a capacitively coupled waveguide. By employing cyclic preparation and measurement protocols, we transform the fluxonium into a precise frequency-resolved charge sensor, boasting a charge sensitivity of 33 μe/√Hz. This translates to an energy sensitivity of 2.8ℏ per hertz, rivaling state-of-the-art transport-based sensors while remaining inherently resistant to dc-charge noise. The large gate-capacitance of our fluxonium-based charge sensor (~50 fF) is highly beneficial in real-world charge sensing applications, where the sensitivity gets diluted when the self-capacitance of the probed system exceeds that of the sensor. This work paves the way for new experimental investigations into quantum phenomena within the 1-10 MHz range, including the strong-coupling regime with macroscopic mechanical resonators
