U of Toronto experiment named top breakthrough of 2011 by Physics World
Date:12/15/2011

Aephraim Steinberg and colleagues at the Centre for Quantum Information and Quantum Control at the University of Toronto had the top physics breakthrough of the year according to Physics World magazine.

Steinberg led an international team in applying a modern measurement technique to the historical two-slit interferometer experiment in which a beam of light shone through two slits results in an interference pattern on a screen behind. That famous experiment and the 1927 debates between Niels Bohr and Albert Einstein, seemed to establish that you could not watch a particle go through one of two slits without destroying the interference effect: you had to choose which phenomenon to look for. Thus the quantum mechanics quandary: how can we know reality if we cannot measure it without distorting it?

With their new experiment, Steinberg's group did what the physics textbooks said was impossible. They succeeded in experimentally reconstructing full trajectories which provide a description of how light particles move through the two slits and form an interference pattern. Their description of the experiment was published in Science and resulted in coverage by the world's science media, including a feature in Physics World. http://physicsworld.com/cws/article/news/46193.

"By applying a modern measurement technique to the historic experiment, we were able to observe the average particle trajectories undergoing wave-like interference, which is the first observation of its kind. This result should contribute to the ongoing debate over the various interpretations of quantum theory," said Steinberg. "It shows that long-neglected questions about the different types of measurement possible in quantum mechanics can finally be addressed in the lab, and weak measurements such as the sort we used in this work may prove crucial in studying all sorts of new phenomena."
