Since the 1920s, Albert Einstein, Niels Bohr and others proposed various thought experiments that demonstrate the breakdown of our classical Newtonian approach to physics when tackling the microscopic quantum mechanical world. We have now reached the level of control and technological expertise at which it is possible to carry out these thought experiments in the lab and verify the predictions of quantum mechanics. In 1992, Lucien Hardy proposed a thought experiment that clearly demonstrated the paradoxes that arise between quantum and classical logic. Recently, we have been able to implement this experiment by precisely producing, manipulating, and detecting single photons, the smallest unit of light. In this talk I will discuss Hardys Paradox as well as the cutting-edge technologies and methods we use to control light in the laboratory. Biography: Krister Shalm is a Ph.D. candidate at the University of Toronto. His primary area of research is into the quantum mechanical nature of light. In his spare time, Krister is an avid swing dancer.   Page Top Copyright © 2004 Subtle Technologies Festival
