qiskit.visualization.plot_error_map

qiskit.visualization.plot_error_map(backend, figsize=(12, 9), show_title=True, qubit_coordinates=None)

Plots the error map of a given backend.

매개변수:

• backend (Backend) – Given backend.

• figsize (tuple) – Figure size in inches.

• show_title (bool) – 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.

반환:

A matplotlib figure showing error map.

반환 형식:

Figure

예외 발생:

• VisualizationError – The backend does not provide gate errors for the ‘sx’ gate.

• MissingOptionalLibraryError – If seaborn is not installed
