qiskit.quantum_info.DensityMatrix.draw

DensityMatrix.draw(output=None, **drawer_args)

Return a visualization of the Statevector.

repr: ASCII TextMatrix of the state’s __repr__.

text: ASCII TextMatrix that can be printed in the console.

latex: An IPython Latex object for displaying in Jupyter Notebooks.

latex_source: Raw, uncompiled ASCII source to generate array using LaTeX.

qsphere: Matplotlib figure, rendering of density matrix using plot_state_qsphere().

hinton: Matplotlib figure, rendering of density matrix using plot_state_hinton().

bloch: Matplotlib figure, rendering of density matrix using plot_bloch_multivector().

Parameters

• output (str) – Select the output method to use for drawing the state. Valid choices are repr, text, latex, latex_source, qsphere, hinton, or bloch. Default is repr. Default can be changed by adding the line state_drawer = <default> to ~/.qiskit/settings.conf under [default].

• drawer_args – Arguments to be passed directly to the relevant drawing function or constructor (TextMatrix(), array_to_latex(), plot_state_qsphere(), plot_state_hinton() or plot_bloch_multivector()). See the relevant function under qiskit.visualization for that function’s documentation.

Returns

matplotlib.Figure or str or TextMatrix or IPython.display.Latex: Drawing of the Statevector.

Raises

ValueError – when an invalid output method is selected.
