Individual Module Demos

python src/qec_steane.py        # QEC simulations

Example Interactions

User: !runsim 0.01
Bot: Simulation: Steane [[7,1,3]] | p_phys=0.0100 | p_log=0.000100 | Improvement: 100x

User: !threshold
Bot: Steane [[7,1,3]] pseudo-threshold: η_thr ≈ 9.30e-05 | Below this rate, QEC provides net benefit

User: !ai What is the Steane code?
Bot: The Steane [[7,1,3]] code is a quantum error correction code that encodes 1 logical 
     qubit into 7 physical qubits. It can correct any single-qubit error...

User: !note E4
Bot: QEC note E4 (MIDI 64, velocity 80)

User: !export threshold
Bot: Exported threshold curve to MIDI: /tmp/qec_threshold.mid
