First Teleportation Over a Large Distance

MIT's image that shows an axis
being rotated. Like, whoa Dude, no way.
According to MIT's blog The Physcis arXiv:
Physicists have teleported quantum information from one ensemble of atoms to another 150 metres away, a demonstration that paves the way towards quantum routers and a quantum Internet
The thing is, measuring qbits destroys them and they only last a 100 microseconds. According to MIT, "[n]one of those challenges seem like showstoppers." Also, there's been short distance teleportation of information before, just not over a long distance like 150 meters (164 yards). There's no indication as to when we get to beam down to planets.

In other news, scientists are seeking a "grand unified theory of flocking" using "laser powered micro sailboats," and "Europe" (by which arXiv means a scientist in Austria) wants to build a quantum optics link to the International Space Station to test the relationship between gravity and quantum mechanics at gravitational scales and to help build a global quantum internet. Saying you're helping a quantum internet apparently gets you big funding.
