From an empty canvas to a real quantum result — in four steps.
Design a circuit by hand or in code, choose a machine, run it, and read an honest result. No queue rituals, no gatekeeping — in your browser or from your own code.
Four steps, start to finish
Everything you need lives on one screen — build, run, and understand without switching tools.
Design your circuit
Drop gates onto a visual canvas — Hadamard, Pauli, rotations, CNOT, CZ and measurement — across qubits and time steps. Prefer code? Write OpenQASM or use the Python SDK; the diagram and the code stay in sync, live.
gates: H · X · Y · Z · S · T · RX · RY · RZ · CNOT · CZ · MChoose a machine
Run instantly on the simulator while you experiment, then send the same circuit to real quantum hardware when you're ready. For hardware you can see the live device topology — which qubits are online and how they connect — so a run never lands on a dead qubit.
RoRo Simulator · instant | RoRo Quantum · real hardwareRun it
Pick how many shots to sample and submit. We transpile your circuit to the machine's native gates, route it onto valid qubits, and track the job end-to-end — queued, running, done — with transparent credit cost shown up front.
shots: 1,000 – 100,000+ · cost shown before you runRead the result
Get an honest, complete picture: the sampling histogram and outcome probabilities, per-qubit Bloch spheres, and the density matrix — all updating live as you build, before you ever spend a credit.

The same circuit runs on both — start fast and free, finish on real qubits.
RoRo Simulator
An exact statevector simulator for fast, free iteration. Perfect for learning, debugging and prototyping before you commit to hardware.
RoRo Quantum
Real superconducting quantum hardware. See the live qubit topology, run on validated qubits, and read measurement statistics from a genuine quantum processor.
Results you can actually read
Not just a number — the full state of your circuit, visualized.
Sampling & probabilities
The outcome histogram and the probability of each measurement result.
Bloch spheres
Each qubit's state as a Bloch vector — pure on the surface, mixed inside when entangled.
Density matrix
The full state as a heat grid — diagonal probabilities and off-diagonal coherences.

It takes about a minute to go from a blank canvas to a measured result.
