Scientists at the University of Geneva in Switzerland have successfully passed 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-kilometers (15-miles) away. This experiment entailed generating a quantum entanglement of two photons using a laser, and then sending one of those entangled photons down an optical fiber while simultaneously sending the other to a crystal. The crystal basically acts as a memory store for the quantum information contained on the transmitted photon. Continue reading for the video news report and more information.
“The quantum state of the two elements of light, these two entangled photons which are like two Siamese twins, is a channel that empowers the teleportation from light into matter,” says Dr. Felix Bussieres, a senior researcher and lead author of the experiment.
