make_rpe_epsilon_str_lists_gx_gz(k_list)

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

These circuits are used to estimate epsilon (X 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:

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

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