Learn how a feature of the quantum world called entanglement is the key to an unbreakable code. Review the counterintuitive rules of entanglement. Then play a game based on The Newlywed Game that illustrates the monogamy of entanglement. This is the principle underlying quantum cryptography..

The uncopyability of quantum information raises the possibility of quantum cryptography - an absolutely secure method for transmitting a coded message. This lecture tells how to do it, noting that a handful of banks and government agencies already use quantum cryptography to ensure the security of their most secret data.

Learn how a feature of the quantum world called entanglement is the key to an unbreakable code. Review the counterintuitive rules of entanglement. Then play a game based on The Newlywed Game that illustrates the monogamy of entanglement. This is the principle underlying quantum cryptography.

Number theory is one of the oldest and largest branches of pure mathematics. Experts of number theory delve deep into the structure and nature of numbers, and explore the remarkable, startling, and often beautiful relationships that exist among them. Gain deep insights into the complex and beautiful patterns that structure the world of numbers, the branches of study that reveal these patterns, and the processes by which great thinkers establish new...

The one-time pad may be in principle unbreakable, but consider the common mistakes that make this code system vulnerable. Focus on the Venona project that deciphered Soviet intelligence messages encrypted with one-time pads. Close with the mathematics behind public key cryptography, which makes modern transactions secure—for now..

A portrait of two very different mathematicians, porridge pulleys and Pi features Fields medalist Vaughan Jones, one of the world's foremost knot theorists and an avid windsurfer, and Hendrik lenstra, a number theorist with a passion for Homer and all things classical. Porridge pulleys and Pi poses the question: how do we get first-rate research mathematicians? Hendrik lenstra and Vaughan Jones have had an extraordinary impact on mathematics; this...
