Information complementarity: A new paradigm for decoding quantum incompatibility

Speaker:	Huangjun Zhu
Time:	11月24号上午10点30分
Address:	物理楼709室
Abstract:	The existence of observables that are incompatible or not jointly measurable is a characteristic feature of quantum mechanics, which lies at the root of a number of nonclassical phenomena, such as uncertainty relations, wave-particle dual behavior, Bell-inequality violation, and contextuality. However, no simple criterion is available for determining the compatibility of even two (generalized) observables, despite the overarching importance of this problem and intensive efforts of many researchers over more than 80 years. Starting from the simple idea that every observable can only provide limited information and that information is monotonic under data processing, we introduce a powerful information theoretic paradigm together with an intuitive geometric picture for decoding incompatible observables. By virtue of quantum estimation theory, we introduce a family of universal criteria for detecting incompatible observables and a natural measure of incompatibility, which are applicable to arbitrary number of arbitrary observables. Based on this framework, we derive a family of universal measurement uncertainty relations, provide a simple information theoretic explanation of quantitative wave-particle duality, and offer new perspectives for understanding Bell nonlocality, contextuality, and quantum precision limit.

Optical technology from Southampton as an enabler of future science, current technology and historical impact

Speaker:	Prof Peter G.R. Smith
Time:	Tue, 2014-06-17 10:00 - 11:30
Address:	Room 111, Physics Buliding, Shanghai Jiao Tong University.
Abstract:	This talk will start with an overview of the Optoelectronics Research Centre at the University of Southampton, and highlight key historical technological breakthroughs made at the University. The talk will discuss how technology developed at Southampton has had major impact on the modern world and show how commercialisation of University technology provides economic impact in the UK and worldwide. By taking recent examples developed within his research group, Prof Smith will show how progress in optical technology is impacting on important areas of science – ranging from sensing of chemical and biological species through to fundamental research into quantum information processing. As well as direct impact from Southampton research the talk will show how commercialisation can lead to major new science through the use of products by research groups worldwide. Prof Smith will demonstrate that outputs from two spin-outs he founded from Southampton – Covesion Ltd and Stratophase Ltd have resulted in new results at major Universities and published in the highest impact journals including Science and Nature.
