Multiplexed quantum memories enable long-distance teleportation.

Researchers at ICFO have achieved long-distance quantum teleportation of information from a photon to a solid-state qubit using a multiplexed quantum memory and an active feed-forward scheme. The architecture is compatible with telecommunications channels, enabling future integration and scalability for long-distance quantum communication. The team plans to extend the setup to longer distances while maintaining efficiency and rates and to use the technique in the transfer of information between different types of quantum nodes for a future quantum internet.
