Three-Node Quantum Network is a Step Towards the Quantum InternetHanson: We realized the world’s first multi-node quantum network, that is, a network that connects small quantum processors using entanglement. Researchers at the Delft University QuTech center created the first multi-node quantum network, which is a step in the direction of building a network of interconnected quantum computers. Next steps are to expand the network with more qubits and different functionality, and in parallel to test the first quantum internet control layers, in particular the link layer. We combine remote quantum nodes based on diamond communication qubits into a scalable phase-stabilized architecture, supplemented with a robust memory qubit and local quantum logic. But without the possibility of relaying the quantum state through some kind of intermediate node, the distance separating the origin and destination qubits was necessarily going to be limited.
