Original title had a "?" at the end. According to the article this was a simulation, not an experiment. (I.e. nobody sent any particles of light anywhere.) From the article: "the researchers (and their team/colleagues) emphasize that their model is mathematically equivalent to a single photon traveling through a CTC. Nothing has actually been sent back through time though"
