Original Message If this is true, it is fvcking amazing - forget the "implementation of practical long-distance quantum communication protocols" part - this means two distinct particles of matter can entangle themselves from the photons they emit.

Entanglement study makes a quantum leap

...physicists at the Ludwig-Maximilians-University in Munich said they had demonstrated that two atoms separated by a distance of about 65 feet could become entangled and trigger an alert to announce that they had done so.

While other experiments have successfully entangled atoms, photons and diamond crystals, this was the first to do so at a long distance and include a signal, or herald, to let scientists know that entanglement had been achieved.
++++++++++
The experiment involved the capture of two rubidium atoms in separate "atom traps" located in different rooms. The traps used lenses and lasers to position each atom and prompt it to emit a stream of photons, or packets of light. The photons were inherently entangled with the atoms that emitted them.
