The IDE for learning
quantum computing

Write quantum circuits in Qiskit, Cirq, or CUDA-Q. Watch them render live. Simulate with one keypress. Learn from an AI tutor that sees your code.

Everything you need to learn quantum

A complete environment designed from scratch for quantum computing students. Not a plugin. Not a notebook. A purpose-built IDE.

Code Editor

Monaco-powered editor with quantum-aware syntax highlighting, autocomplete, and inline error diagnostics.

4 qc = QuantumCircuit(2, 2)
5 qc.h(0)
6 qc.cx(0, 1)

Circuit Visualization

Live-rendered circuit diagrams that update as you type. Every gate, wire, and connection visualized instantly.

Bloch Sphere

Interactive 3D visualization of qubit states. Rotate, zoom, and explore quantum state space in real time.

Probability Display

See measurement probabilities update live after each simulation. Understand quantum outcomes at a glance.

Dirac AI Assistant

AI tutor powered by Claude that sees your code, circuit, and errors. Ask anything about quantum computing.

What does the Hadamard gate do?
It creates an equal superposition of |0> and |1> from a basis state.

Multi-Framework

Write in any major quantum SDK. Nuclei auto-detects your framework from imports.
