Quantum Cryptography: A Tale of Secrets Revealed Through the Laws of Physics

Perimeter Institute brings great thinkers from around the world to Canada to share their ideas on a wide variety of interesting and topical subjects. These lectures and debates are aimed at non-specialists. No mathematical or scientific knowledge is necessary or assumed. Each event is explicitly tailored for the general public and everyone is welcome to attend. (...)

Sensitive information can be valuable to others - from your personal credit card numbers to state and military secrets. Throughout history, sophisticated codes have been developed in an attempt to keep important data from prying eyes. But now, new technologies are emerging based on the surprising laws of quantum physics that govern the atomic scale. These powerful techniques threaten to crack some secret codes in widespread use today and, at the same time, offer new quantum cryptographic protocols which could one day profoundly alter the way we safeguard critical information.

Will big questions be answered when the Large Hadron Collider (LHC) switches on in 2007? What will scientists find? Where might the research lead? Nima Arkani-Hamed, a noted particle theorist, is a Professor of Physics at Harvard University. He investigates a number of mysteries and interactions in nature – puzzles that are likely to have experimental consequences in the next few years via particle accelerators, like the LHC, as well as cosmological observations.

The laws of physics are usually meant to be set in stone; variability is not usually part of physics. Yet contradicting Einstein's tenet of the constancy of the speed of light raises nothing less than that possibility. I will discuss some of the more dramatic implications of a varying speed of light. João Magueijo is Professor of Physics at Imperial College London. He is currently visiting Perimeter Institute and the Canadian Institute for Theoretical Astrophysics in Toronto. He received his doctorate in theoretical physics at Cambridge University, and has been a visiting scientist at the University of California at Berkeley and Princeton University.
