> Abstract: Caesar encrypted his messages by shifting each letter three places
> in the alphabet. Modern computer science was born in the effort to break the
> Nazi Enigma code, and Cold War spies used code books that fit inside a
> walnut. Nowadays, the cryptography we depend on every day — for instance, to
> send our credit card information when we buy something on the Web — relies on
> the mathematics of prime numbers. But in 1994, Peter Shor discovered that a
> future quantum computer could crack our cryptosystems by breaking large
> numbers into their prime factors. Cris will start by describing how these
> cryptosystems work, and how a quantum computer could break them. (Nothing
> beyond high-school math, he promises!) He’ll end by giving 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.
