Note that they are performing a weak measurements, meaning their results do not tell you anything about the trajectory of an individual photon
hmm... My sister had me all atwitter today when she sent me the article.

Though it looks like there's nothing to see.

Odd that their abstract seems to imply something contrary to what you are saying. I guess I'll have to read the full article.

We sent single photons emitted by a quantum dot through a double-slit interferometer and reconstructed these trajectories by performing a weak measurement of the photon momentum, postselected according to the result of a strong measurement of photon position in a series of planes.
And go back to school to find out what a "weak measurement" is.
