Qiskit Metal
Qiskit Metal is an open-source framework for engineers and scientists to design superconducting quantum devices with ease.
Installation
If you are interested in customizing your experience, or if you are unable to install qiskit-metal using the pip install instructions below, consider installing directly the source code, following the instructions in the documentation and/or the installation instructions for developers.
For normal use, please continue reading.
The Qiskit Metal deployed package
You can install Qiskit Metal via the pip tool (a python package manager).
pip install qiskit-metalPIP will handle most of the dependencies automatically and you will always install the latest (and well-tested) version of the package.
Some of the dependencies, namely pyside2 and geopandas, might require manual installation, depending on your specific system compatibility. If you encounter installation or execution errors, please refer first to the FAQ.
We recommend to install qiskit-metal in a conda environment or venv, to prevent version conflicts with pre-existing package versions.
Jupyter Notebook
At this time, we recommend using Jupyter notebook/lab to be able to access all the Qiskit Metal features. Jupyter is not installed with the default dependencies, to accommodate those users intending to utilize a centralized or customized installation.
If you require a fresh installation, please refer to either anaconda.org or jupyter.org.
Unless you installed the entire jupyter package in your current environment, do not forget to create the appropriate kernel to make the environment (thus qiskit-metal) available to jupyter (instructions in the FAQ)
Creating Your First Quantum Component in Qiskit Metal:
Now that Qiskit Metal is installed, it's time to begin working with it. We are ready to try out a quantum chip example, which is simulated locally using the Qiskit MetalGUI element. This is a simple example that makes a qubit.
$ python
>>> from qiskit_metal import designs, draw, MetalGUI, Dict, open_docs
>>> design = designs.DesignPlanar()
>>> design.overwrite_enabled = True
>>> design.chips.main
>>> design.chips.main.size.size_x = '11mm'
>>> design.chips.main.size.size_y = '9mm'
>>> gui = MetalGUI(design)Launch the Qiskit Metal GUI to interactively view, edit, and simulate a QDesign:
>>> gui = MetalGUI(design)Let's create a new qubit (a transmon) by creating an object of this class.
>>> from qiskit_metal.qlibrary.qubits.transmon_pocket import TransmonPocket
>>> q1 = TransmonPocket(design, 'Q1', options=dict(connection_pads=dict(a=dict())))
>>> gui.rebuild()
>>> gui.edit_component('Q1')
>>> gui.autoscale()Change options.
>>> q1.options.pos_x = '0.5 mm'
>>> q1.options.pos_y = '0.25 mm'
>>> q1.options.pad_height = '90um'
>>> q1.options.pad_width = '455um'
>>> q1.options.pad_gap = '30 um'Update the component geometry after changing the options.
>>> gui.rebuild()
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)Closing the Qiskit Metal GUI.
>>> gui.main_window.close()A script is available here, where we also show the overview of Qiskit Metal.
