Science
Run the physics yourself.
Four explainers, each a working instrument. You feel the phenomenon, you run it with your own hands, and then the math proves what you felt.
01The benches — four, all live
Take an instrument. All four are live.
Each page holds one phenomenon, one working bench, and the equations underneath — with every caveat attached.
The Bell test
Two detectors agree more than any pre-written script could arrange. Run the CHSH ritual and watch S pass 2.
CHSH · SHAKE256 · SHA3-256 Open the benchAuthenticated encryption
Seal a message, flip one byte, and watch the whole frame refused. The seal is real and it runs in this page.
ChaCha20-Poly1305 · RFC 8439 Open the benchThe lattice floor
Two independent systems converge on one shared secret. The hard problem underneath is noise in a lattice.
ML-KEM-1024 · X25519 · FIPS 203 Open the benchThe ratchet
Step a real key-derivation chain with your thumb. Old keys die as it turns — and it only turns forward.
SHA3-256 · ChaCha20-Poly1305 Open the bench02The method — feel, touch, understand
Read every bench in the same order.
Feel
The phenomenon first. A section opens with what your senses can take in one glance — the pull comes before the proof.
Touch
The instrument second. You run it yourself: tap to decrypt, run a round, scroll the agreement. A demo is real or it is absent — never an animation posing as crypto.
Understand
The math last. The equations that prove what you felt, in plain mono, with the honest caveats printed beside them.
03The observatory — its own domain, its own instrument
Cross to the observatory. It runs on its own domain.
quantumentanglement.io holds the full Bell laboratory and the signed pulse beacon. The explainers here link into it; the beacon's pulses are the ones our Bell bench fetches and recomputes.
Precision note This is not QKD. Not quantum networking. Not quantum teleportation. We do not violate the no-communication theorem. We bind a key-derivation function to a verifiable physical measurement no classical adversary can fabricate in advance.
04The record — the questions we get asked hardest
The honest questions.
Is anything on these pages simulated?
The encryption demos run real ChaCha20-Poly1305 (RFC 8439) compiled to WebAssembly, self-tested against the RFC's test vector before first use — on any mismatch they refuse to run rather than fake output. The ratchet bench derives its chain with real SHA3-256 in the same module.
The Bell bench is a browser: it holds no photons. It samples the exact
quantum statistics, E = cos 2(a−b), against a genuine
local-hidden-variable model, and says so right on the instrument.
Signed beacon pulses carry a backend label; today it
reads local-sim, and the verifier shows it.
Why does a messenger teach physics?
Every security sentence we publish names a primitive. These pages are where you check us: run the instrument a claim rests on, then read the claim again.
Do I need the math to use QERYX?
The math runs whether you read it or not. These pages exist for the day you decide to verify it yourself — every equation shown is the one the instrument actually computes.
The physics ships in your pocket.
The primitives these pages teach are the ones the messenger runs — ML-KEM-1024 + X25519 key agreement, ChaCha20-Poly1305 seals.
