MIT's Quantum Index Report 2026 compares about 300 quantum processors
MIT's annual report charts the state of quantum computing, including a comparison of around 300 processors. Its benchmarking numbers are mostly reported by the companies themselves, which the report says openly.
MIT's Initiative on the Digital Economy published the Quantum Index Report 2026 this month, a free, openly licensed overview of the field. Its benchmarking chapter compares around 300 quantum processors, 56 of them commercially available.
Among its findings: trapped-ion machines lead on two-qubit accuracy, and IQM's Garnet has the fastest published two-qubit operation. Other chapters cover patents, funding and research activity.
How much weight to give it: it's broad and carefully sourced, but it gathers numbers companies report rather than measuring them, and it says itself that no independently verified universal measure exists. That's the gap QubitBenchmark's evidence grades are meant to fill. See How others rank them for our summary.
Does this change the rankings? No. Rankings only change when QubitBenchmark publishes a checked result in its monthly data release.
