报告题目： From quantum miracles to many worlds
Action at a distance is a miracle. Quantum phenomena such as interaction-free measurements, teleportation, Bell-type correlations apparently require such miracles. Accepting the many-worlds interpretation of quantum mechanics avoids the necessity of action at a distance and thus removes paradoxes from quantum theory.
Lev Vaidman, born in Leningrad, after winning Physics Olimpiad for high-school students in Sovied Union, studied physics in Israel. He received B. Sc. at Hebrew University, M. Sc. at Weitzmann Institute and Ph.D., under guidance of Yakir Aharonov, at Tel Aviv University. His research is centered in foundations of quantum mechanics and quantum information. He is a theoretical physicist, many of his proposals were implemented in laboratories around the world, but recently he himself became involved in experimental realisations of his ideas. Vaidman is mainly known for introducing teleportation of continuous variables, cryptography with orthogonal states, novel types of quantum measurement: nonlocal, weak, protective, interaction-free. His research of interpretations of quantum mechanics centered in developing the many-worlds interpretation, for which he is apparently the strongest proponent.
