    "abstract": "The application of dynamical decoupling pulses to a single qubit interacting\nwith a linear harmonic oscillator bath with $1/f$ spectral density is studied,\nand compared to the Ohmic case. Decoupling pulses that are slower than the\nfastest bath time-scale are shown to drastically reduce the decoherence rate in\nthe $1/f$ case. Contrary to conclusions drawn from previous studies, this shows\nthat dynamical decoupling pulses do not always have to be ultra-fast. Our\nresults explain a recent experiment in which dephasing due to $1/f$ charge\nnoise affecting a charge qubit in a small superconducting electrode was\nsuccessfully suppressed using spin-echo-type gate-voltage pulses.",
