  Quantum networking is an emerging area with the potential to transform
information processing and communications. In this paper, we present a brief
introduction to quantum network control, an area in quantum networking
dedicated to designing algorithms for distributing entanglement (i.e.,
entangled qubits). We start by explaining what qubits and entanglement are and
how they furnish quantum network control operations such as entanglement
swapping and teleportation. With those operations, we present a model for
distributing entanglement in a multi-hop quantum network to enable applications
such as quantum key distribution and distributed quantum computing. We conclude
the paper by presenting open research problems in the field, including the
characterization of the quantum network capacity region and the design of
throughput-optimal policies.
