Wow. Our double-slit experiment published earlier this year in Science has been voted as the top Physics breakthrough of 2011 by Physics World! We are in some good company considering all of the things that have happened this year. Congratulations to Aephraim, Sacha, Boris, Sylvain, Marty, Rich.
But after much debate among the Physics World editorial team, this year's honour goes to Aephraim Steinberg and colleagues from the University of Toronto in Canada for their experimental work on the fundamentals of quantum mechanics. Using an emerging technique called "weak measurement", the team is the first to track the average paths of single photons passing through a Young's double-slit experiment – something that Steinberg says physicists had been "brainwashed" into thinking is impossible.
Honorable mention goes to Jeff Lundeen whose work on a similar experiment comes in second.
