The first successful demonstration of quantum teleportation over a fiber optic cable has been achieved, according to groundbreaking new research. The breakthrough, made by engineers at Northwestern University and funded by the U.S. Department of Energy (DoE), presents new potentials in the realm of quantum communication by allowing it to be combined with existing cables used for providing Internet. This innovative approach reduces the requirement for additional infrastructure needed for quantum computing or quantum sensing technologies. Previously thought to be impossible, the Northwestern team responsible for the breakthrough says their work showcases the next stage in leveraging a single fiber...

Quantum teleportation, once confined to the pages of science fiction, is steadily becoming a tangible scientific achievement. Advances in quantum mechanics over the last decade have transformed teleportation from a theoretical concept into an experimental reality. These breakthroughs have revealed innovative methods for transmitting information instantaneously over vast distances, offering transformative possibilities for computing, communication, and cryptography. Scientists are now closer than ever to bridging the gap between imagination and reality in this cutting-edge field.

Ytterbium ion is the first element to be teleported over a distance. Ytterbium ions have been 'teleported' over a distance of a metre.MM_photo / Alamy Researchers have teleported a single ion of the element ytterbium over a metre in distance, shattering previous records. Photons have gone further but teleportation of matter has only occurred between ions in the same trap over a few micrometers.Although still highly inefficient, their technique provides an important proof-of-principle for long-distance quantum teleportation and brings the era of quantum communication closer to reality. The work appears in the journal Science1.The spandexed crew of Star Trek has...
