Limits RegistryIBM unveiled the IBM Q System One at CES in January 2019, describing it as the first integrated universal quantum computing system for scientific and commercial use: a 20-qubit processor, cryogenics and control electronics enclosed in a 9-foot glass-walled case. Systems have since been installed in Germany, Japan, the United States and elsewhere.

The year IBM unveiled the first self-contained gate-model quantum computer designed for commercial use outside the research lab.
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.
