qCodePlot3D

qCodePlot3D provides 3D visualizations of 2D and 3D quantum color codes, making it easy to inspect the code and visualize syndromes of error configurations.

Available Quantum Codes

The following quantum codes are currently implemented:

• 2D square color code
• 2D triangular color code
• 3D cubic color code
• 3D tetrahedral color code

The package provides an interface to extend it to further quantum codes. Contributions of such implementations to the package are appreciated.

Usage

The package comes with a minimal GUI to construct and plot the predefined quantum codes. Start the GUI by calling

python3 -m qcodeplot3d

After Building a available code with a given distance, you can hit Plot Primary Graph to show it. If you press Build Dual Graph in addition, you can also plot the dual graph or both graphs at once.

Alternatively, the package can be used to script the creation of figures. A small example snipped might look as following:

import pathlib
from qcodeplot3d.cc_3d import TetrahedronPlotter, tetrahedron_3d_dual_graph

THIS_DIR = pathlib.Path(__file__).parent

distance = 5
dual_graph = tetrahedron_3d_dual_graph(distance)
plotter = TetrahedronPlotter(dual_graph, distance=distance)
# describes the position of the camera in the 3D visualization
CPOS = [(333.44920594948127, -92.62132121918515, 221.35429214703458),
        (-1.365808884682137, 1.7594735760392801, -12.072404824078472),
        (0.5292985009453346, 0.7030498941163704, -0.4749357254197479)]
plotter.plot_primary_mesh(
    camera_position=CPOS,
    filename= THIS_DIR / "tetrahedron-d=5-1-primary"
)
dual_graph_mesh = plotter.construct_dual_mesh(
    dual_graph,
    use_edges_colors=True,
    highlighted_edges=dual_graph.edges(),
    highlighted_nodes=dual_graph.nodes()
)
plotter.plot_debug_primary_mesh(
    dual_graph_mesh,
    camera_position=CPOS,
    transparent_faces=True,
    filename= THIS_DIR / "tetrahedron-d=5-2-both"
)
