  In the coming years, quantum networks will allow quantum applications to
thrive thanks to the new opportunities offered by end-to-end entanglement of
qubits on remote hosts via quantum repeaters. On a geographical scale, this
will lead to the dawn of the Quantum Internet. While a full-blown deployment is
yet to come, the research community is already working on a variety of
individual enabling technologies and solutions. In this paper, with the
guidance of extensive simulations, we take a broader view and investigate the
problems of Quality of Service (QoS) and provisioning in the context of quantum
networks, which are very different from their counterparts in classical data
networks due to some of their fundamental properties. Our work leads the way
towards a new class of studies that will allow the research community to better
understand the challenges of quantum networks and their potential commercial
exploitation.
