Quantum Lab
Build a circuit gate by gate, run it on an exact statevector simulator in your browser (nothing is uploaded), read the sampled counts and exact probabilities, export the code in four frameworks, and compare how the same circuit compiles across architectures. Every run is seeded and reproducible. New to circuits? Start with the first lesson; to see what real devices do to your circuit, open the hardware comparison and how the simulator is verified.
Run the simulator to see sampled counts and the exact state.
Sharing produces a URL that encodes the circuit itself — nothing is stored on a server. The library persists in this browser and syncs to your account when you’re signed in. The simulator is capped at 24 qubits and refuses larger circuits before allocating memory.
