     "An ideal DDS is defined as a sequence of instantaneously-applied pulses, which correspond to instantaneous rotations of the Bloch sphere. However, in reality, the rate of rotation is limited by the `maximum_rabi_rate` and/or `maximum_detuning_rate` for a given pulse. Due to this limiting factor, the target rotation is implemented over a control segment with finite duration. Q-CTRL Open Controls converts a `DynamicDecouplingSequence` into a `DrivenControl` before exporting the resulting `DrivenControl`. This conversion requires the `maximum_rabi_rate` and `maximum_detuning_rate` to be specified and raises an error if the conversion is not successful (e.g. if control segments overlap due to a low `maximum_rabi_rate` or `maximum_detuning_rate`).\n",
