Add gates, see the probabilities shift in real time, then measure to collapse the state. This runs the actual state-vector math on your device — no hardware, no hype.

Measuring picks one outcome at random, weighted by the bars above.
// Real classical simulation of real quantum math — accurate for these small circuits. // Beyond ~30 qubits this approach becomes impossible on any classical machine. That gap is the whole point of quantum hardware. // To run on actual qubits, the same circuit would go to IBM Quantum, AWS Braket, or Azure Quantum via their APIs.
