What it does
A short text message is encoded to bits and run through simulated T1-decay bit-flip noise over time, with a choice of protection: none, a 3-qubit repetition code (majority vote), or a Steane [[7,1,3]] code, rendered live against an interactive Fano-plane geometry visualizer showing which of the seven qubits are hit as errors accumulate. An optional dynamical-decoupling toggle extends the effective coherence time. Watching the same message survive, garble, or get corrected side by side makes the point a static diagram usually has to explain in words: error correction isn’t a guarantee, it’s a shifted failure threshold.
