Within about 8-10 years of this interview (by roughly 2033-2035), his company (and the broader field) will scale superconducting quantum computers to be large and reliable enough (heading toward million-qubit-class, error-corrected systems) to solve genuinely hard, useful problems.
“what we want to do and it's a timeline of many other groups is to do something in let's say in the next 8 10 years something like that... in a let's say 10-year time scale something like that” View on YouTube
Explanation
This is an 8-10 year forecast (to roughly 2033-2035) made in October 2025 for reaching large-scale, useful quantum computing. As of August 2026 the field remains at roughly the hundred-qubit scale Martinis described, well short of the million-qubit-class systems he outlined, and the timeframe has not elapsed, so this cannot be evaluated yet.
