Clifford Paterson Lecture By Professor Sandu Popescu University of Bristol
One of the most exotic aspects of the behaviour of microscopic particles, such as electrons, atoms, photons is the so-called quantum non-locality. Microscopic particles which have interacted in the past and then moved far from each other, remain, in a certain sense, still connected, and can instantaneously "communicate" with each other (in apparent but not real contradiction with Einstein's relativity). In his talk Sandu will explain this quantum non-locality at a very popular level (with NO mathematics). He will also present some of the uses of non-locality for quantum information and communication - strange effects such as teleportation - and will discuss the implications of non-locality for understanding the very foundations of quantum mechanics.
