In Spain’s Canary Island chain, researchers from all over Europe generated a polarization-entagled photon pair with the twin sent over an optical free-space link to Tenerife about 144 kilometers (90 mi) away where the Ground Station of the European Space Agency acted as a receiver. Previously 13km was the record on similar experiments.
Quantum entanglement is a property of particles, such as photons, to become entangled with each other, behaving like psychically connected twins. Even at vast distances a disturbance on one affects the other. This was even predicted and labelled “spooky interaction” by Albert Einstein himself.
If this technology continues on these records, we could be seeing satellite-based quantum communication and experiments on quantum physics in space in addition to ubiquitous instantanenous communication across light years. Think of the instantaneous communication in the Star Trek TV shows over many light years.
