How this list is built
We rank by expected attendance because it's the closest proxy we have for prominence — bigger events draw bigger speakers, more sponsors, and (usually) more substantive deal flow. Where attendance isn't known, the event drops below ranked entries even if it's well-regarded. If you want raw inventory instead of a curated list, the quantum computing conferences hub has every event in the database, not just the top 25.
Total in this category: 37 events.
