As if the idea ideas of quantum entanglement and time travel werent difficult enough to wrap ones head around separately, two physicists at the Universtiy of Queensland in Australia have further compounded the headache by merging the two ideas via a new kind of quantum entanglement that links particles not across space, but across time.
Quantum entanglement is that spooky action (Einsteins words, not ours) that links two particles such that a measurement on one immediately influences the state of the other, even if the two particles are separated by miles, or even light years. Entanglement defies the intuitive way we understand the universe to work (as does most of quantum mechanics). The idea of time teleportation, as described by S. Jay Olson and Timothy Ralph, doesnt add clarity but it does introduce some interesting questions about the fundamentals of the universe.
In a sense, everyone and everything is time traveling, moving forward in time at a given rate. What Olson and Ralph propose is that its possible to take a shortcut into the future without being present in the interim. How? Tech Reviews KFC explains:
The idea is that a detector acts on a qubit and then generates a classical message describing how this particle can be detected. Then, at some point in the future, another detector at the same position in space, receives this message and carries out the required measurement, thereby reconstructing the qubit.

Thought it was interesting. Would like to see it again. Bad title.
I wanna time travel back to when the constitution was being written and write in there things to keep progressiveness out of it.

When these “scientists” deliver me my anti-grav flying car, THEN they can start playing with time travel.
Yes...”The Welfare Clause shall not be construed in the 20th Century as a means for politicians to buy votes. Nor shall it be construed in the 20th Century as a means for erecting an unsustainable welfare state comprised of blood-sucking leeches.”
That should do it.
I've always maintained that most UFOs are time travelers coming back to gawk at their primitive ancestors.
And don't forget niggardly, the worst of all.
The first three words of this sentence demonstrate how very ignorant we still are.
It's the eleven herbs and Spice.
Yes. And that rate or speed is infinite. Here's why: The present--i.e. now--is an infinitely small moment, succeeded by another infinitely small moment, etc. In an infinitely small moment, the entire cosmos is in the past--is gone. And in an infinitely small moment of time the present is created and destroyed. In a real sense, we are traveling through time at the speed of infinity. The Hindu's are right.

So, if these guys get us stuck in some endless “Groundhog Day” loop, we all go find Olson and Ralph, right? Beating them senseless time and time again might get boring after a while, but we could do it in shifts.
Einstein’s remark was an objection to “spooky action-at-a-distance”. Mutilating it by omitting the -at-a-distance qualifier is just stupid.
Of course, Einstein’s objection turns out to have been wrong, as actually carrying out the EPR experiment showed, and worse still, one can’t get “local realism” because Bell’s Inequalities are violated in nature.
Whoops! Edit to say: “Beating them senseless time and time again will NEVER get boring.”
Not quite. It's a Planck scale time interval called a "Planck unit". It's the time required for light to travel 1 Planck length. Roughly 10-43 (10 to the minus forty third) seconds.
Flux capacitor needed.
Wouldn’t that be: can you hear me then?
