How to use options

This section explains how to use the options available in circuit_drawer.

Text-Based Drawing

Numbering the gates

Set verbose to True. (Default: verbose=False)

>>> circuit_drawer(circuit, output_method='text', verbose=True)
   ___     ___     ___
  | X |   |DeM|   |CX |
--|000|---|003|---|004|----------
  |___|   |   |   |___|
   ___    |   |     |
  | Y |   |   |     |
--|001|---|   |-----|------------
  |___|   |___|     |
   ___              |      ___
  | Z |             |     | X |
--|002|-------------●-----|005|--
  |___|                   |___|

Change the control dot style

In default, character “●” is used to mean control qubit. But in CommandPrompt, sometimes display layout is corrupted. In this case, please use the character “.”(dot="small") instead of the character “●”(dot="large").

Use the dot. large and small are available. (Default: dot="large")

>>> circuit_drawer(circuit, output_method='text', dot="small")
   ___     ___     ___
  | X |   |DeM|   |CX |
--|   |---|   |---|   |----------
  |___|   |   |   |___|
   ___    |   |     |
  | Y |   |   |     |
--|   |---|   |-----|------------
  |___|   |___|     |
   ___              |      ___
  | Z |             |     | X |
--|   |-------------･-----|   |--
  |___|                   |___|

Matplotlib Drawing

Change image size

Use the dpi, scale option to change the image size. (Default: dpi=72, scale=0.6) In most cases, use scale, but adjust the dpi if you want to generate a sharper image.

>>> circuit_drawer(circuit, output_method='mpl', dpi=72, scale=0.6)

LaTeX Drawing

Change image size

Use the ppi option to change the image size. (Default: ppi=150)

>>> circuit_drawer(circuit, output_method='latex', ppi=150)
