By mapping the input angle to the range ``]-180, 180]`` (where -180 is excluded), it ensures that the output amplitude is always minimized on the hardware. This mapping should not have an effect on the qubit in general. -180 degrees is excluded to ensure positive amplitudes in the gates like X180 and Z180. Note that an input of -180 degrees is remapped to 180 degrees to maintain the positive amplitude constraint. :param theta: The rotation angle in degrees. This angle will be mapped to the interval ``]-180, 180]``. :type theta: float :returns: The mapped angle in degrees, which will be in the range ``]-180, 180]``. This mapping ensures the output amplitude is always minimized for transmon operations. :rtype: float .. rubric:: Example ``` >>> _modulo_360_with_mapping(360) 0.0 >>> _modulo_360_with_mapping(-180) 180.0 >>> _modulo_360_with_mapping(270) -90.0 ```
