Cris Moore Explores the Future of Cryptography in a Quantum Era 🔐

Cryptography has come a long way since invisible ink and decoder rings. Today we rely on the magic of prime numbers to keep our online transactions and records secure. I'll describe cryptosystems work, from Caesar to the Kama Sutra to modern e-commerce, and how a future quantum computer would break them. I'll then describe what kinds of cryptography might remain secure even after quantum computers are built. Nothing beyond high school math, I promise!
