Great Debate and Quantum Physics to be Explored by Leading Scientist Visiting Canada's Perimeter Institute

    WATERLOO, ON, Oct. 1 /CNW/ - Many experts are convinced that large scale,
practical implementations of quantum information systems hold great promise
for society, much as the laser and the transistor have already revolutionized
the world. This stems from a long history of research that included an
intense, raging battle of epic proportions between scientific giants.
    This debate will be examined by Alain Aspect of the Institute d'Optique
and Ecole Polytechnique, Palaiseau, France, during a Perimeter Institute
Public Lecture to be held on Wednesday, October 3rd, 2007 at 7:00 pm in
Waterloo, Ontario.
    In tracing the history, Aspect will explain why Albert Einstein and Niels
Bohr argued over the nature of "entangled" states - where pairs of sub-atomic
particles are strangely correlated - from 1935 until their very deaths. He
will also share how, decades later, John Bell discovered his famous
inequalities that made it possible for experimentalists, including Alain
Aspect and others, to settle the great debate and help propel a new era of
fundamental understanding with concepts and methods that seek to harness
unique properties of atoms to process and transmit information.


    Prof. Alain Aspect is a leading figure with the Centre National de la
Recherche Scientifique (CNRS, France's National Center for Scientific
Research) where he is Senior Scientist at Institut d'Optique and Professor at
Ecole Polytechnique. Both institutions are on the same campus at Palaiseau.
Among his many awards and honours, Prof. Aspect is recipient of the 2005 CNRS
Gold Medal, the highest academic recognition in France, as well as a member of
the Académie des Sciences and the Académie des Technologies.


    Perimeter Institute is an independent, non-profit research centre where
international scientists are clustering to push the limits of our
understanding of physical laws by contemplating and calculating new ideas
about the very essence of space, time, matter and information. The Institute,
located in Waterloo, Ontario, also provides a wide array of educational
outreach activities for students, teachers and members of the general public
across Canada and beyond in order to share the joys of research, discovery and
innovation. For more information, please visit
