Articles like this on the internet are usually completely garbage, but Natalie is a really fantastic journalist. If you’re worried about woo because of the title, there isn’t any here (and quanta magazine is generally great for coverage of science)

tldr: there’s a calculation you can perform in quantum mechanics that suggests particles can tunnel through barriers faster than they could have traveled through free space at the speed of light. Scientists have now measured this more precisely, and this effect seems to hold up, but is still very small, so it’s hard to understand the ramifications of this for things like causality.

I wish more science journalists were like this. Able to not get all the core facts wrong.

Right, articles like this are often short on crucial details, it's speculation until we see the research papers.

Re causality etc., as I mentioned above, if the duration of wavefunction collapse can actually be measured then this puts a whole new spin on the matter (sorry, puns aren't my forte but it seemed appropriate here). ;-)

Update, FYI, I've just found some links about the matter and posted them above. These describe an experiment where an electron was seen transiting smoothly between two energy states whilst being in two places at once.
