Peter Shor’s 1994 discovery of his quantum factoring algorithm ignited the practical field of quantum computing, showing for the first time that quantum machines could outperform classical computers on real-world problems. In this 5-minute conversation with 9-year-old Kai, Shor explains—in simple, human terms—how quantum computers can break big numbers into prime factors, and why that breakthrough continues to shape the future of cybersecurity, finance, and global business strategy.
