- Logical qubits
- Not confirmed: The maker's pages reviewed do not report a demonstrated logical-qubit count for Nighthawk r2, nor identify a code and paper for such a demonstration.
- Two-qubit gate fidelity
- Not confirmed: The available-processor table reports “2Q error (best)” as 8.936E-4 for ibm_phoenix, but does not print a two-qubit gate fidelity in percent. The error rate is not converted to fidelity.
- One-qubit gate fidelity
- Not confirmed: The maker's Nighthawk pages reviewed do not print a one-qubit gate fidelity in percent.
- The maker’s own metric
- Not confirmed: its line was not found on its page, and a second reading did not confirm it
