Abstract
Quantum networking allows the transmission of information in ways unavailable in the classical world. Single packets of information can now be split and transmitted in a coherent way over different routes. This aggregation allows information to be transmitted in a fault tolerant way between different parts of the quantum network (or the future internet) - even when that is not achievable with a single path approach. It is a quantum phenomenon not available in conventional telecommunication networks either. We show how the multiplexing of independent quantum channels allows a distributed form of quantum error correction to protect the transmission of quantum information between nodes or users of a quantum network. Combined with spatial-temporal single photon multiplexing we observe a significant drop in network resources required to transmit that quantum signal - even when only two channels are involved. This work goes far beyond the concepts of channel capacities and shows how quantum networking may operate in the future. Further it shows that quantum networks are likely to operate differently from their classical counterparts which is an important distinction as we design larger scale ones.
