QubitForge
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.
#6d4bd6 Distributed-narrative cast
Meet the cast
QubitForge is text-forward (R-OLDER-TEEN-DN-ADAPTED, ages 15–18) — no illustrated cast; the 'characters' are the four gates whose behaviour IS the quantum idea. X (NOT) swaps the two amplitudes — purely classical. H (Hadamard) spreads amplitude evenly into a 50/50 superposition, and applied twice it interferes back to certainty. Z (phase) flips the sign of the |1⟩ amplitude — invisible to a single measurement, yet it changes what later gates do. CNOT flips a second qubit only when the first is 1; combined with H it entangles two qubits into a Bell pair that always agree. Every amplitude is computed exactly on-device (real state-vector arithmetic), so nothing here is hand-waved. Illustrated portraits/chapters/audio are N/A for the older-teen band, not a follow-on.
X (NOT gate)
Swaps the two amplitudes — |0⟩ becomes |1⟩; the purely classical bit-flip
H (Hadamard gate)
Spreads amplitude evenly into a 50/50 superposition; applied twice the two paths interfere and cancel back to |0⟩ — the heart of quantum computing
Z (phase gate)
Flips the sign of the |1⟩ amplitude — a phase a single measurement cannot see, but which changes what later gates do
CNOT (controlled-NOT)
Flips a second qubit only when the first is 1; with H it entangles two qubits into a Bell pair — measure one and you instantly know the other
