Alice & Bob, "Defining the Logical Qubit: Five Criteria to Benchmark Logical Qubit Claims", June 2026.
⚠ verdicts derived from a simulated noise model — this is a demonstration of the criteria machinery, not a hardware claim
| criterion | verdict | reason |
|---|
| sufficient_cycles | pass | |
| all_runs_counted | pass | |
| breakeven | not evaluable | no physical baseline available (ideal simulation has no meaningful physical comparator) |
| scalable_parameters | not evaluable | zero logical errors observed at adjacent distances (d3->d5): suppression is unresolved at this shot count, not demonstrated |
| utility_timescales | not evaluable | memory experiment ran 5 rounds, far below the utility threshold of 1000000 rounds; this experiment cannot speak to application timescales |
