Tools panel¶

The Tools panel sits on the left side of the canvas and holds everything you can drag onto your workspace, grouped into three collapsible sections: Tools, Ready circuits, and Assets:

Tools, Ready circuits, and Assets sections, collapsed

Expanding Tools reveals three categories, Basic, Upload, and Quantum:

Tools panel expanded, showing Basic, Upload, and Quantum categories

Basic¶

Simple shapes and text for sketching layouts or annotating a canvas:

Text - a text label with its own rich formatting toolbar, see Text
Rectangle, Circle, Triangle - basic shapes with a fill/stroke/opacity toolbar, see Shapes
Quiz - an embeddable multiple-choice question block, see Quiz

Upload¶

Bring outside files onto the canvas, see Upload blocks:

Image - image files
PDF - PDF documents
Python - Python scripts
OpenQASM - OpenQASM files

Quantum¶

The quantum-specific building blocks that make Qanvas more than a plain whiteboard:

Operations - a gate catalog block, see Operations
Circuit - a circuit-building block with quantum and classical registers, see Circuit
Coding - shows a circuit's code, see Coding
Bloch sphere - a per-qubit Bloch sphere visualization, see Bloch sphere
Q-Sphere - a Q-Sphere visualization, see Q-Sphere
Results - a results/output block, see Results

Ready circuits¶

Below the Tools categories, Ready circuits is its own collapsible section holding a library of prebuilt circuits you can drop directly onto the canvas, see Ready circuits.

Assets¶

Assets lists everything you've uploaded or saved into the current workspace, with a count next to the section title, so you can reuse a file you've already added without uploading it again, see Assets.
