- Scientists achieved quantum teleportation of a photon's state between two separate quantum dots over a 270-meter free-space link.
- The experiment demonstrated high fidelity (up to 82 ± 1%) and involved a decade of collaboration across European research institutions.
- This breakthrough marks a key step toward building quantum networks, including future quantum relays and a quantum internet for secure communication.
- The success relied on strategic planning, advanced technology like GPS synchronization, and deterministic quantum dot sources.
