In a recent study published in the esteemed journal Nature Communications, researchers from the Institute of Photonic Sciences (ICFO) in Spain have accomplished quantum teleportation. Led by ICREA Prof. at ICFO Hugues de Riedmatten, Dario Lago-Rivera, Jelena V. Rakonjac, and Samuele Grandi were able to transfer quantum information from a photon to a solid-state qubit stored in a multiplexed quantum memory over a long distance.
Quantum teleportation is a technique that transfers quantum information from one location to another. Unlike science fiction’s portrayal of physical objects being teleported, quantum teleportation only transfers quantum information. The sender is not required to have knowledge of the specific quantum state being transferred, and the recipient’s location can be unknown. However, classical information must be sent from the sender to the receiver to complete the quantum teleportation process, and as a result, quantum teleportation cannot occur faster than the speed of light.
Quantum teleportation has gained significant interest in the field of quantum communications and quantum networks. It enables the transfer of quantum bits between network nodes over long distances using previously shared entanglement. This could lead to the integration of quantum technologies into current telecommunication networks and extend the ultra-secure communications enabled by these systems to very long distances. Additionally, quantum teleportation enables the transfer of quantum information between different kinds of quantum systems, such as between light and matter or between various types of quantum nodes.
