QubitHub Documentation

Open for builders

QubitHub is open — anyone can create an account, no waitlist. See the Account & Email Verification guide for what to expect after you sign up.

Start building

Install the CLI

pip install qubithub-sdk
qubithub login

Push circuits from your terminal — the CLI Quickstart walks you through the first 5 minutes.

Try in the browser

No install needed — browse the curated library, fork a circuit, edit it inline, and execute on Qiskit / Cirq / PennyLane simulators. See the Web UI Guide.

Publish a circuit

Push over git (HTTPS) or via qubithub circuits push. Every circuit is a real repository — clone, fork, diff, history. See the Contributing Circuits guide + manifest reference.

Learn quantum

Pair with Claude Code via our MCP Agent Skills — circuit scaffolding, review, and interactive learning paths grounded in the curated library.

Supported frameworks

Qiskit (IBM), Cirq (Google), and PennyLane (Xanadu) execute natively in the QubitHub sandbox — same qubithub.toml manifest, same execution dialog, framework-specific runners. Domains covered include algorithms, QML, optimization, chemistry, error correction, quantum information, and hardware benchmarking. Hardware backends are on the post-beta roadmap; today’s executions land on simulators.

What’s new

The latest release carries the changelog for every shipped feature. See the Run Lifecycle reference for what happens between submission and results, and the Account & Email Verification guide for the first-time-user flow.
