Quantum Computing Visualizer
Drop gates onto a circuit; watch a 3-qubit register's amplitudes evolve in real time.
Quantum mechanics is best taught by watching it happen. The visualizer is a 3-qubit register and a gate palette: H, X, Y, Z, S, T, CNOT. Drag a gate onto a wire, drop, see the state vector update — magnitudes and phases — and the Bloch-sphere of each qubit re-orient. Run a small Grover circuit on a custom oracle. Watch entanglement appear as off-diagonal correlations.
For the curious: in 30 minutes, you have a working physical intuition that takes a textbook 3 chapters.
