Good question. I don't understand a bit of what they're saying in the article but I have wondered before about the question. Maybe it is impossible for people to time travel but I wonder about information.

So are you saying time is an illusion? Just curious.

The problem was, Bacon's quantum computer was travelling around 'closed timelike curves'.
There is a caveat -- not all physicists think that these open timeline curves are any more likely to be realisable in the physical universe than the closed ones.

When we touch a basketball, it takes "time" for the signal to reach our brains, and to respond with action that takes even more time (if we're trying to dribble per say).

It might be worth some people spending a little money to see if they can build a receiver to pick up signals from Earth's future. I'm not sure how to go about it, though. One thing that might make it a little easier is that we know exactly in the sky where the Earth will be at any point in the future, and we can point our trans-temporal radio telescopes at that point.
Maybe the future people will even help us out by sending a message back to us. If they're not destroyed, of course.
