Magic State Distillation: 2D Error-Suppression Map

Every fault-tolerant quantum computer needs the non-Clifford T gate to be universal, but T gates can't be protected by stabilizer codes the way Clifford gates can — instead, noisy copies of the "magic state" they consume are purified through distillation circuits. This 2D view renders the Bravyi–Kitaev 15-to-1 protocol as a pannable, zoomable ring diagram: fifteen noisy input states converge into a single higher-fidelity output state at the centre, while a live log-scale chart in the corner traces the error rate collapsing as ε_out ≈ 35·ε_in³ per round across up to three chained rounds.
