VIDEO: What is Post-Quantum Cryptography

Each lock eventually meets a key, and today’s cryptography is no exception. For decades, our digital world has relied on mathematical puzzles that even the fastest computers struggle to solve. But quantum machines threaten to tear through those puzzles in seconds.

That’s why researchers are racing to build a new shield, post-quantum cryptography, designed to secure everything from your banking app to national defence in an era where quantum power could break the rules of security overnight.

In this video, you’ll explore what it is, why it matters, and how it could reshape the future of online trust.
