Researchers in Germany have demonstrated quantum entanglement of two atoms separated by 33 km (20.5 miles) of fiber optics. This is a record distance for this kind of communication and marks a breakthrough towards a fast and secure quantum internet.
Quantum entanglement is the uncanny phenomenon where two particles can become so inextricably linked that examining one can tell you about the state of the other. Stranger still, changing something about one particle will instantly alter its partner, no matter how far apart they are. That leads to the unsettling implication that information is being “teleported” faster than the speed of light, an idea that was too much for even Einstein, who famously described it as “spooky action at a distance.”
Despite its apparent impossibility, quantum entanglement has been consistently demonstrated in experiments for decades, with scientists taking advantage of its bizarre nature to quickly transmit data over long distances. And in the new study, researchers from Ludwig-Maximilians-University Munich (LMU) and Saarland University have now broken a distance record for quantum entanglement between two atoms over fiber optics.
In their experiments, the team entangled two rubidium atoms kept in optical traps in two different buildings on the LMU campus. They were separated by 700 m (2,297 ft) of fiber optics, which was extended out to 33 km with extra spools of cable. Each atom was excited with a laser pulse, which causes it to emit a photon that’s quantum entangled with the atom.
The photons are then sent down the fiber optic cables to meet at a receiving station in the middle. There, the photons undergo a joint measurement, which entangles them – and because they’re each already entangled with their own atom, the two atoms become entangled with each other as well.

Something to ponder:
Joh_3:13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
That’s why Einstein called it “spooky”.......................
Well they are telling us that they are “entangled” though. So how do they know? If it’s just because they created them together, then I am not very convinced. Show me some test that shows they are entangled at that distance.
