CPW Launch Pad¶

Preparations¶

The next cell enables module automatic reload. Your notebook will be able to pick up code updates made to the qiskit-metal (or other) module code.

[1]:

%reload_ext autoreload
%autoreload 2

Import key libraries and open the Metal GUI. Also we configure the notebook to enable overwriting of existing components

[2]:

from qiskit_metal import designs, draw
from qiskit_metal import MetalGUI, Dict, Headings

design = designs.DesignPlanar()
gui = MetalGUI(design)

# if you disable the next line, then you will need to delete a component [<component>.delete()] before recreating it
design.overwrite_enabled = True

[3]:

from qiskit_metal.qlibrary.terminations.launchpad_wb_coupled import (
    LaunchpadWirebondCoupled,
)

[4]:

# Explore the options of the LaunchpadWirebondCoupled

LaunchpadWirebondCoupled.get_template_options(design)

{'layer': '1',
 'trace_width': 'cpw_width',
 'trace_gap': 'cpw_gap',
 'coupler_length': '62.5um',
 'lead_length': '25um',
 'pos_x': '0um',
 'pos_y': '0um',
 'orientation': '0'}

[5]:

# Setup the launchpad location and orientation
launch_options = dict(
    pos_x="990um", pos_y="2812um", orientation="270", lead_length="30um"
)

lp = LaunchpadWirebondCoupled(design, "P4_Q", options=launch_options)

gui.rebuild()
gui.autoscale()

[6]:

# Get a list of all the qcomponents in QDesign and then zoom on them.
all_component_names = design.components.keys()

gui.zoom_on_components(all_component_names)

[7]:

# Look at the options of the launch pad in QDesign.
lp.options

# Save screenshot as a .png formatted file.
gui.screenshot()
