make_rpe_model(alpha_true, epsilon_true, y_rot, spam_depol, gate_depol=None, with_id=True)#

Make a model for simulating RPE, parameterized by rotation angles.

Note that the output model also has thetaTrue, alpha_true, and epsilon_true added attributes.

Parameters:

  • alpha_true (float) – Angle of Z rotation (canonical RPE requires alpha_true to be close to pi/2).

  • epsilon_true (float) – Angle of X rotation (canonical RPE requires epsilon_true to be close to pi/4).

  • y_rot (float) – Angle of rotation about Y axis that, by similarity transformation, rotates X rotation.

  • spam_depol (float) – Amount to depolarize SPAM by.

  • gate_depol (float, optional) – Amount to depolarize gates by (defaults to None).

  • with_id (bool, optional) – Do we include (perfect) identity or no identity? (Defaults to False; should be False for RPE, True for GST)

Returns:

The desired model for RPE; model also has attributes thetaTrue, alpha_true, and epsilon_true, automatically extracted.

Return type:
