## Entangling remote qubits using the single-photon protocol

### An in-depth theoretical and experimental study

The generation of entanglement between remote matter qubits has developed into a key capability for fundamental investigations as well as for emerging quantum technologies. In the single-photon, protocol entanglement is heralded by generation of qubit-photon entangled states a ...

We report on the realization of a multi-node quantum network. Using the network, we have demonstrated three protocols; generation of a entangled state shared by all nodes, entanglement swapping and quantum teleportation between non-neighboring nodes.

@enFuture quantum internet applications will derive their power from the ability to share quantum information across the network^{1,2}. Quantum teleportation allows for the reliable transfer of quantum information between distant nodes, even in the presence of highly loss

Quantum networks can enable quantum communication and modular quantum computation. A powerful approach is to use multi-qubit nodes that provide quantum memory and computational power. Nuclear spins associated with defects in diamond are promising qubits for this role. However, ...

The distribution of entangled states across the nodes of a future quantum internet will unlock fundamentally new technologies. Here, we report on the realization of a three-node entanglement-based quantum network. We combine remote quantum nodes based on diamond communication ...

Entanglement-based quantum networks will provide exciting opportunities for science and engineering. Here, we report the realization of a three-node quantum network by generating distributed multi-partite entangled states and performing entanglement swapping through an interme ...
