1.6 QComponent Shape Library¶

Quantum Metal ships a set of sample shape QComponents — subtract polygons, spirals, n-gons, and hollow rectangles — that are useful for:

Custom chip features (flux bias lines, wirebond pads, markers)
Prototyping arbitrary geometries before writing a full QComponent
Teaching: each shape shows a minimal QComponent implementation

This notebook demonstrates each shape on a fresh design.

from qiskit_metal import designs, MetalGUI
import qiskit_metal as qm

%matplotlib inline

design = designs.DesignPlanar()
design.overwrite_enabled = True

Basic and crazy shapes.

See their source code to see how to get started on a few simple examples.

[60]:

from qiskit_metal.qlibrary.sample_shapes.n_square_spiral import NSquareSpiral

# print(NSquareSpiral.get_template_options(design))
ops = {
    "n": "10",
    "width": "10um",
    "radius": "100um",
    "gap": "22um",
    "pos_x": "0.65mm",
    "pos_y": "2.2mm",
    "orientation": "0",
    "subtract": "False",
}
NSquareSpiral(design, "spiral", ops)
NSquareSpiral(
    design, "spiral_cut", {**ops, **dict(subtract=True, width="22um", gap="10um")}
)
gui.rebuild()

To see source, try ??NSquareSpiral. Go to the actual source file and edit it, copy it, or edit it in the GUI using the Edit Source button.
