Quantum Optics Group Seminar, 2:00 - 3:00 pm, 114 East Bridge
"Where is the Quantum Particle between two Measurements?" Professor Lev Vaidman, Tel Aviv University. More information: http://www.tau.ac.il/~vaidman/

ABSTRACT: Wheeler Delayed Choice experiment, Elitzur-Vaidman Interaction-free Measurement, and Hosten-Kwiat Counterfactual Computation will be discussed to answer Bohr's forbidden question: "Where is a quantum particle while it is inside a Mach-Zehnder Interferometer?" The analysis reveals a paradoxical feature of a pre- and post-selected quantum particle: it can reach a certain location without being on the path that leads to and from this location.
