make_rpe_alpha_str_lists_gx_gz(k_list)

Make alpha cosine and sine circuit lists for (approx) X pi/4 and Z pi/2 gates.

These circuits are used to estimate alpha (Z rotation angle).

Parameters:

k_list (list of ints) – The list of “germ powers” to be used. Typically successive powers of two; e.g. [1,2,4,8,16].

Returns:

• cosStrList (list of Circuits) – The list of “cosine strings” to be used for alpha estimation.

• sinStrList (list of Circuits) – The list of “sine strings” to be used for alpha estimation.
