class AccreditationCircuits(target_circ, two_qubit_gate='cx', coupling_map=None, seed=None)

This class generates accreditation circuits from a target.

Implementation follows the methods from Samuele Ferracin, Theodoros Kapourniotis and Animesh Datta New Journal of Physics, Volume 21, November 2019 https://iopscience.iop.org/article/10.1088/1367-2630/ab4fd6

Initialize the circuit generation class parse into layers

Parameters

• target_circ (QuantumCircuit) – a qiskit circuit to accredit

• two_qubit_gate (string) – a flag as to which 2 qubit gate to compile with, can be cx or cz

• coupling_map (list) – some particular device topology as list of list (e.g. [[0,1],[1,2],[2,0]])

• seed (int) – seed to the random number generator

__init__(target_circ, two_qubit_gate='cx', coupling_map=None, seed=None)

Initialize the circuit generation class parse into layers

Parameters

• target_circ (QuantumCircuit) – a qiskit circuit to accredit

• two_qubit_gate (string) – a flag as to which 2 qubit gate to compile with, can be cx or cz

• coupling_map (list) – some particular device topology as list of list (e.g. [[0,1],[1,2],[2,0]])

• seed (int) – seed to the random number generator

Methods

__init__(target_circ[, two_qubit_gate, …])	Initialize the circuit generation class parse into layers
generate_circuits(num_trap)	Generate quantum circuits for accreditation
target_circuit(target_circ[, …])	Load target circuit in to class, and parse into layers

generate_circuits(num_trap)

Generate quantum circuits for accreditation

Parameters

num_trap (int) – number of trap circuits

Returns

A tuple of the form

(circuit_list, postp_list`, v_zero) where: circuit_list (list): accreditation circuits postp_list (list): strings used for classical post-processing v_zero (int): position of target circuit

Return type

tuple
