Abstract
Decoherence of Josephson qubits can be substantially reduced by
tuning their parameters to optimal operation points, with only quadratic
coupling to fluctuations. We analyze dephasing due to 1/f noise for a
two-level system, detuned from an optimal point, i.e., the crossover to the
linear-coupling regime, both for free induction decay and for spin-echo
experiments. Influence of several noise sources is also discussed.
