pygsti.circuits.rpecircuits.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.

pygsti.circuits.rpecircuits.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.

pygsti.circuits.rpecircuits.make_rpe_theta_str_lists_gx_gz(k_list)

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

These circuits are used to estimate theta (X-Z axes 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

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

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

pygsti.circuits.rpecircuits.make_rpe_string_list_d(log2k_max)

Creates a dictionary containing all the circuits needed for RPE.

This includes circuits for all RPE cosine and sine experiments for all three angles.

Parameters

log2k_max (int) – Maximum number of times to repeat an RPE “germ”

Returns

totalStrListD (dict) – A dictionary containing all circuits for all sine and cosine experiments for alpha, epsilon, and theta. The keys of the returned dictionary are:

• ’alpha’,’cos’ : List of circuits for cosine experiments used to determine alpha.

• ’alpha’,’sin’ : List of circuits for sine experiments used to determine alpha.

• ’epsilon’,’cos’List of circuits for cosine experiments used to

determine epsilon.

• ’epsilon’,’sin’ : List of circuits for sine experiments used to determine epsilon.

• ’theta’,’cos’ : List of circuits for cosine experiments used to determine theta.

• ’theta’,’sin’ : List of circuits for sine experiments used to determine theta.

• ’totalStrList’ : All above circuits combined into one list; duplicates removed.
