# BB84 · Quantum Key Distribution · instrument № 07

**What it is.** a key no eavesdropper can steal — verified: 25% intercept error, 11% abort, all computed live

**How it works.** The Bennett–Brassard 1984 protocol run live: real state preparation and basis-projected measurement, sifting, QBER, and an intercept-resend eavesdropper.

**The live example.** This emergent does not merely describe a tool — it links its working self: **[run instrument № 07 live](https://davidwise01.github.io/mimzy/bench/07-bb84.html)**. Open it, operate it, and the badge's claims execute in front of you.

**The verified record.** Verified: ~50% sift survival, 25% Eve-induced error, 11% abort threshold — all computed by the simulation, not hard-coded.
