Cryptography has come a long way since invisible ink and secret decoder rings. Today we rely on the magic of prime numbers to keep our online transactions and records secure. 

On April 13 in Santa Fe, SFI Professor Cris Moore gave an SFI community lecture titled "Sending Secrets: Security and Cryptography In a Quantum World" in which he describes the history of cryptography from the era of the Romans to the present, discusses how modern cryptosystems work and how a future quantum computer would break them, and provides a personal view about whether quantum computers can be built – and what kinds of cryptography could remain secure even if and when they are built.

Generous support for this SFI public lecture was provided by Los Alamos National Bank and Joy and Philip LeCuyer.
