Features
Everything you need to learn quantum
Circuit Visualization
Live-rendered circuit diagrams that update as you type. Every gate and wire, visualized instantly.
Bloch Sphere
Interactive 3D visualization of qubit states. Rotate, zoom, and explore state space in real time.
Probability Display
Measurement probabilities update live after each simulation. Understand outcomes at a glance.
Dirac AI Assistant
An AI tutor that sees your code, circuit, and errors. Ask anything about quantum computing.
Multi-Framework
Write in any major quantum SDK — Qiskit, Cirq, CUDA-Q, or Q#. Nuclei auto-detects from imports.
Compatibility
One IDE. Every framework.

Workflow
Three steps to quantum
01
Write
Write quantum code with autocomplete, highlighting, and instant error feedback.
02
Visualize
Circuit, Bloch sphere and histogram update live as you type. No re-runs.
03
Learn
Ask Dirac to explain concepts, debug your circuit, or generate exercises.
New in v0.7.0
Also doing real quantum research?
Switch to Research mode for multi-file projects, declarative parameter-sweep experiments, QEC Studio (Stim circuits, sinter campaigns, threshold and Λ plots, resource estimation), and reproducible run manifests — with Dirac as a terse collaborator instead of a tutor. Learn mode stays exactly as it is.
