Browser-based quantum workbench
Learn quantum computing
Build real circuits, simulate hardware-realistic device noise, and get AI feedback on your reasoning — right in the browser.
Visualise
Manipulate qubits on an interactive Bloch sphere before equations appear.
Build
Drag gates onto real circuit diagrams; the simulator runs instantly.
Noise
Enable device-twin noise calibrated to real hardware to see decoherence.
Evaluate
Submit your reasoning; our AI model grades explanations, not just outputs.
Interactive workbench
A circuit builder that feels like an IDE
Write circuits with a drag-and-drop interface or in OpenQASM. Live histograms update on every gate change.
