Play ShiftForge →
QubitForge
Ages 15–18 · Gr 9–12 Level 4
A qubit is just two numbers. A gate rotates them. Measurement squares them. That is the whole of quantum — no mysticism, exact arithmetic. Start in |0⟩, apply a gate, and predict the odds: 100%? a 50/50 coin? Watch two Hadamards cancel back to certainty (interference), then entangle two qubits into a Bell pair that always agree. QubitForge enumerates the exact amplitudes on your device. Ages 15–18.
