What we mean by Quantum Supremacy
How this timeline is built
Every milestone and prediction comes from primary sources (papers, official announcements, government documents) or reputable newsrooms. Each source is stored with a short literal quote, and those quotes are checked automatically against the original pages. Company announcements stay marked as "claimed" until they are independently confirmed, and every prediction keeps its original deadline, so delays stay visible.
