long-distance teleportation between two atoms: first between atoms 1 meter apart

Hopefully this demonstration will lead the way to quantum computing and pretty much instantaneous communication through an unlimited distance. Very profound implications here. The number of calculations a quantum can do in one clock tick is staggering. This seems like it might lead the way into the next “internet”. The medium being one that we can’t even grasp yet.. perhaps dark matter? This might mean instantaneous communication between every human at the same time via thought.

In a side note, physicists have also invented an entanglement filter. The filter allows two protons through only if their states are the same. This observation supposedly does not change the state of the entangled photons.
via Quantum technologies move a step closer with the demonstration of an ‘entanglement’ filter.

For the first time, scientists have successfully teleported information between two separate atoms in unconnected enclosures a meter apart – a significant milestone in the global quest for practical quantum information processing.

“Our system has the potential to form the basis for a large-scale ‘quantum repeater’ that can network quantum memories over vast distances,” says group leader Christopher Monroe of JQI and UMD. “Moreover, our methods can be used in conjunction with quantum bit operations to create a key component needed for quantum computation.” A quantum computer could perform certain tasks, such as encryption-related calculations and searches of giant databases, considerably faster than conventional machines. The effort to devise a working model is a matter of intense interest worldwide.

D-Wave Still Trying to Prove they have a Quantum Computer

“While founded in 1999, D-Wave remains a start-up because it has yet to ship a computer that customers can actually buy. Much of the company’s work is locked in the theoretical realm of quantum computing – long considered a sort of black arts backwater of the computing field full of promise but thin on near-term practicality.”

I have heard plenty of news about this company and how it’s been trying to prove that it created a quantum computer for years now. Somehow I’m still a bit skeptical just like that company, Steorn, that says they created something that creates energy from nothing (or at least nothing we understand).
