past and future entangled?

<p><a href="http://www.physorg.com/news/2011-01-physicists-method-timelike-entanglement.html">Physicists describe method to observe timelike entanglement</a></p>
<p>(PhysOrg.com) -- In "ordinary" quantum entanglement, two particles possess properties that are inherently linked with each other, even though the particles may be spatially separated by a large distance. Now, physicists S. Jay Olson and Timothy C. Ralph from the University of Queensland have shown that it's possible to create entanglement between regions of spacetime that are separated in time but not in space, and then to convert the timelike entanglement into normal spacelike entanglement. They also discuss the possibility of using this timelike entanglement from the quantum vacuum for a process they call "teleportation in time."</p>
