内容:

Information is physical, so the laws of physics impose the ultimate limits on the information processing. In fact, laws of quantum mechanics both limited and expanded the possibilities for computing, communication and metrology. However, non-relativistic quantum mechanics is only a low-energy limit of relativistic quantum field theory; moreover, the standard information carriers --- photons – are the most relativistic particles that exist. As a result, by analyzing relativistic scenarios with our information carriers we understand the new limitations and exciting possibilities for the information processing. On the other hand, information-theoretical ideas are universal. Their careful application to the problems of relativistic physics can shed light on some of it mysteries, like black hole information loss problem.



人物介绍:

Daniel Terno is currently an Associate Professor at the Department of Physics and Astronomy. He completed the undergraduate and graduate studies at the Technion -- Israel Institute of technology in Haifa, Israel, under guidance of Asher Peres. Daniel received the Ph.D. degree in 2003. He has authored numerous high impact manuscripts in quantum information, foundations of quantum theory and relativistic physics, including the authorities review on the interface of quantum information and relativity theory [1].

Works of Terno, Asher Peres and collaborators initiated studies of relativistic aspects of quantum information and established relativistic quantum information as a branch of quantum info science, as well as led the systematic application of information theory to black hole physics and quantum gravity.

In quantum foundations, investigations of Peres and Terno on the interactions between quantum and classical systems established the standard benchmarks that consistent dynamical schemes should satisfy, and severely restricted domains of their validity. The most important contribution to quantum foundation is a quantum version of the delayed-choice experiment, which gave an impetus to the whole branch of theoretical and experimental studies (Cover story, New Scientist, 2 Jan 2013)

Apart from physics, Daniel's hobbies include sport and reading. Gym, Thai boxing, MMA, and diving are among the former, with a normal Sydneysider's addition of sailing and surfing. Mythology, comparative religion and Ancient, Medieval and Far Eastern history feature among the latter.
