DynamicDecouplingSequence.export_to_file(filename, file_format='Q-CTRL expanded', file_type='CSV', coordinates='cylindrical', maximum_rabi_rate=6.283185307179586, maximum_detuning_rate=6.283185307179586)[source]

Prepares and saves the dynamical decoupling sequence in a file.

  • filename (str) – Name and path of the file to save the control into.

  • file_format (str) – Specified file format for saving the control. Defaults to ‘Q-CTRL expanded’. Currently it does not support any other format. For detail of the Q-CTRL Expanded Format consult DrivenControl.export_to_file().

  • file_type (str, optional) – One of ‘CSV’ or ‘JSON’. Defaults to ‘CSV’.

  • coordinates (str, optional) – Indicates the coordinate system requested. Must be one of ‘cylindrical’ or ‘cartesian’. Defaults to ‘cylindrical’.

  • maximum_rabi_rate (float, optional) – Maximum Rabi rate. Defaults to \(2\pi\).

  • maximum_detuning_rate (float, optional) – Maximum detuning rate. Defaults to \(2\pi\).


ArgumentsValueError – Raised if some of the parameters are invalid.


The sequence is converted to a driven control using the maximum Rabi and detuning rate. The driven control is then exported.
