讲座题目：Quantum Puzzles: From Foundations to Applications
报告人：Prof. ANTON ZEILINGERVienna Center for Quantum Science and Technology, University of Vienna & Austrian Academy of Sciences, Austria
摘要：The development of quantum physics – arguably the most successful description of nature ever – was accompanied by fundamental debates from the early days until today. Schrödinger’s cat, Einstein’s “spooky action at a distance” and his comment that “God does not play dice with the Universe” are deeply rooted in fundamental features of the theory: superposition, entanglement and randomness. The concept of Quantum Information encompasses these fundamental features. In the talk, I will discuss some fundamental experiments. These will include, for example, quantum teleportation, entanglement swapping, delayed choice experiments and quantum communication. The decision whether two photons which share no common past are entangled or not can be made at the time when they already have been detected.
Finally, I will discuss tests of Bell's inequality including a recent Cosmic Bell Test experiment, where the randomness is taken from fluctuations of light from distant quasars. The talk will conclude with The Big Bell Test involving 100.000 participants providing independent input for 13 experiments on 5 continents.
报告人简介：Prof. ANTON ZEILINGER was born in Austria, 1945. He obtained Ph.D degree in 1971 at the University of Vienna. He was a full professor of physics at Technical University of Munich in 1988 to 1989, at University of Innsbruck in 1990 to 1999. From 1999 to present, he has been a full professor at University of Vienna. From 2004 to 2013, he was a director of Institute for Quantum Optics and Quantum Information, Austrian Academy of Sciences. From 2013 till now, he has been a President of Austrian Academy of Sciences. Prof. Zeilinger’s research interests include fundamental phenomena in Quantum Mechanics and their applications in quantum information science and technology. He is the experimental pioneer in quantum information and quantum mechanics. In 1997, he and his team firstly realized quantum teleportation experiment, this work is the milestone in quantum information. Due to his remarkable achievements and contribution, he was awarded many honors including the Wolf prize in Physics 2010.
