sccircuitbuilder 0.0.1

A graphical user interface to create superconducting circuits intended to accompany scQubits

Superconducting Circuit Builder

This is a GUI for designing superconducting circuits intended to accompany the Python package scQubits.

Installation

• git clone https://github.com/benmcdonough20/CircuitBuilder.git
• pip install pyside2

Usage

Start by running python circuitbuilder.py. The elements used to build a circuit are

1. Capacitor
2. Inductor
3. Josephson Junction

Drag the icons from the toolbox onto the canvas to place down an element. Drag nodes together to connect them. Left-click on wires to add anchor points and drag the anchor points to guide the wires.

Keyboard

• Shift + Right Click - add to selection
• Shift + Right Drag - add box to selection
• Enter on property entry box - change property

Mouse

• Left Button Drag on whitespace - pan
• Scroll Wheel - zoom
• Left Button Drag on element/selected group - move selection
• Right Button Drag - box selection
• Left Button Click on element - rotate
• Right Button Click on element - select and show properties

Features

• Split (reverse-join) nodes
• Delete elements
• Wire anchor points
• Undo / Redo
• Save / Open
• Export to scQubits circuit format
• Pre-made circuit library

Dependencies

• Python 3.10.8
• PySide2 5.15.8
• Numpy 1.22.4

Known issues

There are still many bugs!

• Right click has no activation distance, so using a mouse will result in some dropped right clicks
• Sometime import/undo/redo (the memento-based functionalities) crash, but usually they seem to work
