Integer Fluxonium Qubit
We describe a superconducting qubit derived from operating a properly designed fluxonium circuit in a zero magnetic field. The qubit has a frequency of about 4 GHz and an energy relaxation quality factor Q≈0.7×10^{7}, even though the dielectric loss quality factor of the circuit components is in the...
