Built by a quantum lover.
Learning in public.

QCollapses exists because quantum computing is full of misconceptions — in papers, talks, and sometimes in my own research. This site makes those ideas explicit, tests them openly, and improves them in public.

Transparency

Some content on this site — including paper summaries, case explanations, and demos — is written or assisted by AI. The featured paper selection will also be assisted by an AI agent in the future. Every scientific claim is reviewed, but mistakes can still happen. If you find one, please report it.

What this site offers

QCollapses is free, ad-free, and requires no account. It is built for students, researchers, and engineers who want honest quantum computing resources. The simulator runs entirely in your browser, and new cases and papers are added regularly.

Simulator roadmap

The current simulator uses state-vector simulation in the browser. It is designed for learning and experimentation, but does not yet support density matrices, hardware noise models, qubit routing, or Qiskit/OpenQASM export. Phase 2 will add noise simulation, hardware backends, and circuit export using server-side infrastructure.

Support

QCollapses will stay free. Donations help cover hosting, development, and the next generation of the simulator.
