Type a message. It becomes 16 quantum amplitudes, modulated into shots on real quantum hardware, and decoded back into text — with a fidelity witness you can audit. Not a simulation: a channel with honest noise.
Every number below is measured from the fleet's runs on real hardware. The channel is noisy and we say so.
Your text is compressed into 16 amplitudes — a small vector that still carries the shape of the message. Fewer amplitudes mean less to corrupt.
Each amplitude becomes a modulation scheme on the qubits, sampled with roughly 125 shots per amplitude — about 2,000 shots per message. Shot noise is the channel.
Shot counts are demodulated back into amplitudes, then into text. The decoder never invents content it can't find in the shots — it returns what the channel actually carried.
Every round trip mints a witness receipt with the pearson score and the shot envelope. Same-message fidelity runs r = 0.62–0.67 at 2,000 shots.
The 0.77 is the honest limit: two different prompts decoded through the channel correlate at r = 0.77 — the channel has a real memory of its own. We publish that number so you trust the others.
