# Genuine quantum networks with superposed tasks and addressing

@article{MiguelRamiro2021GenuineQN, title={Genuine quantum networks with superposed tasks and addressing}, author={J. Miguel-Ramiro and A. Pirker and Wolfgang D{\"u}r}, journal={npj Quantum Information}, year={2021}, volume={7}, pages={1-15} }

We show how to make quantum networks, both standard and entanglement-based, genuine quantum by providing them with the possibility of handling superposed tasks and superposed addressing. This extension of their functionality relies on a quantum control register, which specifies not only the task of the network, but also the corresponding weights in a coherently superposed fashion. Although adding coherent control to classical tasks, such as sending or measuring—or not doing so—is in general…
