Could this technique allow time travel at least in the future (quantum zeno effect) ?

I forget, are you one of the people on this forum hoping to time-travel and break the laws of physics?
It's fatal to read popular science accounts of things like quantum physics:
The problem with this article is that it doesn't tell you the whole story, and what is actually being observed. There's more than one "observable". For example, you can measure the position or the momentum of a particle; but you can't measure both to arbitrary precision. This is true of any pair of "non-commuting observables" (of which position-momentum is only one example) by Heisenberg's Uncertainty Principle.
You can think of making measurements as being like riding out into the ocean, chasing after a wave. If you are stationary, the waves move up and down, up and down, and if you close your eyes, and open them at a random time, they might be up or down, you can't say.
But if you ride with the wave, it appears to be a stationary, a solid object -- like a particle -- and any time that you open your eyes, you will see that elevated hump of water in exactly the same position. When you ride with the wave like that, you might say that you have been "entangled" with it; and it appears to behave qualitatively differently than if you are stationary. And that's somewhat similar to how it works in quantum physics: when you make a measurement, you become entangled with the system you are measuring in a particular way; and different types of measurement produce different types of entanglement.
