Quantum QuirkVis 🙃

A python package that draws quantum circuits written in qasm/OpenQASM 3.0 and outputs as SVG with a strong focus on personalization.

Features

• SVG output
• Theming engine (JSON)
• Personalization (night mode, custom colors)
• Gate symbol substitutions (emojis, icons, animations)
• Awesome "dial" for parametrized gates
• Animations and other CSS filters
• Lightweight

Themes

Default

Night

Matrix

Emoji

Installation

pip install quirkvis

Usage

from quantum_quirkvis import draw

qasm_str = """
OPENQASM 3.0;
qubit[2] q;
h q[0];
cx q[0], q[1];
"""

draw(qasm_str, theme="matrix", filename="path/to/file.svg")

# or

svg = draw(qasm_str, theme="matrix")

Personalization

Check the themes json files to see how much you can customize, you can customize anything!

Then create your own theme, you don't need to overwrite all the file, you only have to change the values of interest, the rest if defaulted.

• mytheme.json

{
    "name": "default",
    "styles": {
        "background": "#777777",
    }
}

then simply

draw(qasm_str, theme="mytheme.json")

You can also use the cli provided which exposes the command qasmvis

qasmvis ghz.qasm -t matrix -o ghz.svg

or

qasmvis ghz.qasm -t matrix > ghz.svg

or

cat ghz.qasm | qasmvis -t night > ghz.svg

Libraries

The current package just requires pyqasm to parse the qasm files or string into the AST that is processed to create SVG with the selected theme.

Limitations

Currently the library "unrolls" the circuit, therefore complex or custom gates (like CY, Toffoli, CSWAP, etc) are drawn as their primitives.

U-n gates are not yet supported
