A successful test in passing information from light into matter – using the teleportation of the quantum state of a photon via optical fiber cable to a receiving crystal located over 25 km (15 mi) away – has been claimed by physicists at the University of Geneva. This test shattered the same team’s previous record and may herald the development of greater, long-distance teleportation techniques and qubit communications and computing capabilities.
Researchers working at TU Delft's Kavli Institute of Nanoscience in the Netherlands claim to have successfully transferred data via teleportation. By exploiting the quantum phenomenon known as particle entanglement
, the team says it transferred information across a 3 m (10 ft) distance, without the information actually traveling through the intervening space.
An international team of researchers has achieved an important theoretical result by finding that quantum teleportation – the process of transporting quantum information at the speed of light, which could in theory be used to teleport macroscopic objects and, one day, even humans – can be achieved in a much more energy-efficient way than was previously thought.
