Breakthrough in teleportation furthers quantum network development

Innovations have been developed that facilitate quantum teleportation between nodes in a quantum network that do not neighbour each other, paving the way for complex network configurations.

In the quantum communications networks of the future, stationary quantum bits (qubits) made from atoms, ions and various other types of matter will form network nodes for applications such as quantum computing. The remarkable process of teleportation will be used to send quantum information between these stationary qubit nodes. A major challenge for researchers and developers is how to implement teleportation across the network as it grows and becomes more complex. Writing in Nature, Hermans et al.¹ report a demonstration of quantum teleportation between stationary qubit nodes that are not directly connected by a quantum channel — a key step towards reaching far-flung nodes and so fully harnessing the power of a quantum internet²^,³.
