qiskit.visualization.plot_error_map

qiskit.visualization.plot_error_map(backend, figsize=(15, 12), show_title=True, qubit_coordinates=None)GitHub(opens in a new tab)

Plots the error map of a given backend.

Parameters

  • backend (Backend) – Given backend.
  • figsize (tuple(opens in a new tab)) – Figure size in inches.
  • show_title (bool(opens in a new tab)) – Show the title or not.
  • qubit_coordinates (Sequence) – An optional sequence input (list or array being the most common) of 2d coordinates for each qubit. The length of the sequence much mast the number of qubits on the backend. The sequence should be the planar coordinates in a 0-based square grid where each qubit is located.

Returns

A matplotlib figure showing error map.

Return type

Figure

Raises

Example

from qiskit.visualization import plot_error_map
from qiskit.providers.fake_provider import GenericBackendV2
 
backend = GenericBackendV2(num_qubits=5)
plot_error_map(backend)
