High-Coherence Fluxonium Qubit
We report superconducting fluxonium qubits with coherence times largely limited by energy relaxation and reproducibly satisfying T_{2}>100 μs (T_{2}>400 μs in one device). Moreover, given the state-of-the-art values of the surface loss tangent and the 1/f flux-noise amplitude, the coherence...
