  We present the architecture and analyze the applications of a
metropolitan-scale quantum network that requires only limited hardware
resources for end users. Using NetSquid, a quantum network simulation tool
based on discrete events, we assess the performance of several quantum network
protocols involving two or more users in various configurations in terms of
topology, hardware and trust choices. Our analysis takes losses and errors into
account and considers realistic parameters corresponding to present or
near-term technology. Our results show that practical quantum-enhanced network
functionalities are within reach today and can prepare the ground for further
applications when more advanced technology becomes available.
