Quantum Teleportation across a Network - 2022
We have used teleportation to send quantum information across our rudimentary quantum network. Our quantum network is composed of three nodes, connected in a line. Teleportation was used to send the quantum information over a quantum link between the outer nodes. To establish this quantum link, the middle node was required to link the outer two. This first of its kind is an important step towards a future quantum Internet. The results were published on May 25 in Nature.
