Fig. 2: Impact of fluxnoise on coherence.
From: Effects of surface treatments on flux tunable transmon qubits
Flux (Φ) dependent measurements are used to determine coherence parameters related to fluxnoise. a Qubit frequency as a function of Φ. b T1 and \({T}_{2}^{{{{\rm{e}}}}}\) recorded as a function of flux. c flux dependent echo decay rate \({{{\Gamma }}}_{2,{{\Phi }}}^{{{{\rm{e}}}}}\) as a function of the flux sensitivity.
