Lesson 094: Cross-vendor fidelity comparisons
Focus
Assume every diagram must map to topology and basis gates—not textbook abstractions alone. Token Cross-vendor fidelity comparisons:94 keeps neighbouring lessons differentiable.

| Artefact | Honesty check |
|----------|---------------|
| Exact statevector (n<21) | qubit ceiling note |
| Noisy emulation | pauli/channel parity |
| Device trace | leakage / crosstalk tag `low` |
Hypothesis `success amplification lift` ties lesson 94 to observables not vibes.
