The researchers observed that single photons that completely penetrated the stack passed through in about 12.84 femtoseconds. If the team added an additional single layer of low refractive index material to the stack at the end the photon took an additional 3.52 femtoseconds to pass through the stack.In my opinion, no, the word "appears" is a big clue. Plus, it required going through a refractive layer to achieve such speed. The interference between the waves altered the tests too.
However, if the team added a single high refractive index layer to the end of the stack the single photons were able to pass through the entire stack in 5.34 femtoseconds. With the photon passing through the stack in 5.34 femtoseconds the photon appears to travel at faster than light speeds.
Most importantly, the low amount of photos being able to make such speeds made it statistically irrelevant. More studies will be needed.
