The researchers made sure to point out that these are just simulations, albeit successful ones programmed in the known behaviors of entangled particles.

So even though it effectively proved a way to change the results of an experiment in the past, 25% of the time at least, its ability to achieve a form of backward time travel still shouldn't necessarily be compared to a certain Flux Capacitor-equipped DeLorean built by a certain Doc Emmet Brown.
