Computing with many encoded logical qubits beyond break-even
ArXiv
Claim as recorded
48-94 encoded logical qubits demonstrated beyond break-even on trapped-ion hardware: 94 logical qubits via a high-rate error-detecting code, and 48 logical qubits via two-level concatenated quantum error correction. Two separate experiments on the same hardware and in the same paper, different codes -- not additive capacity.

This is a probabilistic model of CRQC capability based on public evidence. Its primary result is a forecast interval built from the percentiles the evidence can resolve. A percentile that does not cross within the model’s horizon is reported as undefined, never estimated, together with the share of scenarios that do not cross. The model is recalculated weekly and does not claim day-level or second-level certainty.
