Quantum Money Teleportation and Computation New Mysteries from the Quantum World Courtesy of Eric Heller Steven Girvin Department of Physics and Applied Physics Yale University Friday, Sept. 7, 2007 10:30 a.m., Red Auditorium

In the world of quantum mechanics, the Heisenberg Uncertainty Principle is a key feature that for many years was thought of as a limitation or disadvantage.  Physicists have recently come to realize that quantum uncertainty can in fact be a useful resource to encrypt information securely, create quantum money that cannot be counterfeited, teleport quantum states from one place to another, and build quantum computers that can solve certain problems exponentially faster than classical computers.  This talk is an elementary introduction to these ideas and describes current experimental attempts to construct the quantum bits that might someday form the building blocks of a practical quantum computer.

NOTE: This talk requires no prior knowledge of quantum mechanics.
