- Announced
- Not confirmed: two readings disagree: 2024-06-05 and 2023-05-09
- Modality
- Trapped ion — docs.quantinuum.com, read 16 October 2026
- Physical qubits
- 56 qubits — docs.quantinuum.com, read 16 October 2026
- Logical qubits
- Not confirmed: The System Model H2 product page and product data sheet do not state a logical-qubit count together with an error-correcting code and its paper. The press release mentions four reliable logical qubits on a 32-qubit machine, but does not identify the code in that statement.
- Two-qubit gate fidelity
- Not confirmed: The product page prints “>99.9%” for two-qubit gate fidelity but does not name a statistic such as median, average, or best. The product data sheet reports infidelity, not fidelity, so that value is not converted.
- One-qubit gate fidelity
- Not confirmed: The product page prints “>99.99%” for single-qubit gate fidelity but does not name a statistic such as median, average, or best. The product data sheet reports infidelity, not fidelity, so that value is not converted.
- The maker’s own metric
- Not confirmed: not found on the maker’s own pages
