Quantum multiplexing for quantum networking and distributed quantum computation

Tomorrows future quantum-internet will need to support a wide range of operations including those arising from quantum-communication, distributed quantum computation and quantum remote sensing tasks. Such applications require the transmission of quantum information across the network where channel losses are a serious problem. Here we introduce the concept of quantum multiplexing to reduce the severity of this issue where multiple-qubits of information are encoded onto each transmitted photon. We will show how one not only saves on the number of photons needed but also on the physical resources required within the network nodes. We will discuss the implementations of quantum multiplexing in various networking applications.
