What else you could use
We are not the only ones measuring.
We are the only ones issuing a verdict you can cite. Here is everyone else, named, with links. Use whichever answers your question.
| What it measures | Who can use it | What it leaves open | |
|---|---|---|---|
| DARPA QBIStage B since Nov 2025 | Whether a manufacturer’s architecture can reach useful scale by 2033. Twenty companies evaluated; eleven in Stage B. | Program participants only. | It does not adjudicate published claims, does not answer for your use case, and its horizon is 2033. |
| Quantum Advantage TrackerIBM + Algorithmiqsince Nov 2025 | Active, superseded and baseline candidates across three tracks, with circuits and data attached. As of 10 Sep 2026: 47 entries and more than fifteen contributing organizations. | Anyone, open. | A manufacturer launched it. It does not require a criterion pre-registered by a third party or budget parity, and no entry carries a signatory. Across the 47 entries there is none where an outside team re-runs another team’s experiment. |
| MetriqUnitary Foundationsince Mar 2026 | Device performance across vendors: more than ten computers, open and versioned dataset. | Anyone, free. | It measures machines, not claims. No mandatory classical champion, no seal, no verdict. |
| QED-Cchecked 10 Sep 2026 | Application standards and benchmarks by consortium consensus. | Consortium members. | Consensus, not judgment: the format does not contemplate anyone signing a verdict that discomfits a member. |
| The vendor’s own benchmarks | What the vendor decided to measure. | Everyone. | The vendor picks the baseline, the budget and the metric. It is the origin of the problem, not the solution. |
| Consultancies, or doing it in-house | What the client wants to know. | Whoever pays, or whoever has the team. | Nobody in that chain loses money if the diagnosis is wrong. |
Which one you need
Which one you need
- “Is this device good?”
- Use Metriq — it is free and open.
- “Has anyone challenged this circuit?”
- The Quantum Advantage Tracker is the best public record there is.
- “Does this claim survive, and can I put that in writing?”
- That is us.

We mirror and link these sources. Every entry we index credits its origin. We built on their work; we did not replace it.
