Prof. Hasegawa of Vienna University of Technology Lectures at Okayama University

February 19, 2013

 Professor Yuji Hasegawa of the Vienna University of Technology, who in January 2012 proved in an experiment new facts that have overturned the long-held Heisenberg Uncertainty Principle, a fundamental element of quantum physics, visited Okayama University on February 15 to give a seminar entitled "Beyond the Heisenberg Uncertainty Principle."
 This principle was first put forth by Professor Werner Heisenberg of Germany in 1927 and is a fundamental principle that is found at the beginning of quantum physics textbooks. Due to the many ambiguities surrounding the principle, proofs and counter-proofs have been bandied around over many long years, until Professor Masanao Ozawa of Nagoya University announced the Ogawa Uncertainty Formula to finally overturn the principle. Professor Hasegawa proved this formula through his experiments, becoming a major news item in the process.
 The lecture was realized through the invitation of Professor Naoshi Ikeda of the Okayama University Graduate School of Natural Science and Technology. Professor Hasegawa gave a clear and succinct description of the process of his experiments to prove the Ogawa Uncertainty Formula, and explained how this verification will have a major impact on society through the development of quantum computers, quantum encoding technology and applications to computational finance. The students and researchers of Okayama University attending the lecture made many questions and comments, with an intense discussion being held.
