Title: What does a photon really look like?

Speaker: Dr. Charles Bamber, National Research Council of Canada

Abstract: The question of how a photon would appear is a complicated by the
fact that the photon is the medium of appearance. One way to see it is to
make the photon shine a little bit of its own light on itself. We use a weak
measurement technique to measure the wavefunction of a photon, a method that
is, in principle, applicable to any quantum particle. This concept has been
generalized and preliminary results will be presented of a measurement of a
mixed state photon as well as a measurement of the evolution of this mixed

Bio: Charles Bamber received his PhD from the University of Rochester in 1991. As a postdoc he was involved in the first measurements of non-linear Compton scattering that were made at the Stanford linear accelerator. After a stint in industry, he joined the National Research Council of Canada in 2005, and currently works in the Photometry and Radiometry group. In 2011, he coauthored a paper on the first direct measurement of a quantum wavefunction.
