Quantum Repeater Extends Entanglement Reach to 50 km
For the first time, physicists from the Universities of Innsbruck, Austria, and Paris-Saclay, France, have integrated all the essential features of a distant quantum network in a single device. Using this technology, scientists were able to send quantum information across a distance of 50 kilometers in a proof-of-principle experiment. This suggests that the components of … Read more
