not yet, but Roland Piquepaille points to an excellent interview with Michio Kaku about time travel. He's very serious about:

"In the last 10 years, there has been enormous progress in something called quantum teleportation. This is not science fiction anymore. Now, to be real, we're not talking about sending Captain Kirk across space and time. But we are talking about sending individual photons across space. In a few decades, maybe we will teleport the first virus, if the virus consists of a few thousand molecules. But at the present time, that's the limit of what we can do. And we can only teleport things in space, not time. But the concept of faxing matter is not totally out of the question. And that was also raised in my book. So there is a little bit of truth there."
