Limits RegistryPUBLIC RECORD
Limits RegistryD-Wave's Advantage system, launched in September 2020, has more than 5,000 superconducting flux qubits connected by the Pegasus topology with 15 couplers per qubit, the largest qubit count of any commercial quantum annealer. Its successor Advantage2 trades qubit count (about 4,400) for higher connectivity and coherence. Annealers are not gate-based universal quantum computers.

The largest physical qubit count of a commercially available quantum annealing processor.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
