Is anyone researching time travel?
Dr. Seth Lloyd, an MIT professor and self-described "quantum mechanic," describes the quantum mechanics behind time travel during a guest lecture at the Institute for Quantum Computing, University of Waterloo (www.iqc.ca). Recorded on Nov. 4, 2010, this is entire lecture entitled "Sending a Photon Backwards in Time."
Dr. Lloyd also sat down for a one-on-one interview at IQC, during which he discusses the weirdness (and beautiful simplicity) of quantum mechanics, and the incredible importance of quantum information research. Excerpts from this interview are below:
