  We review recent advances towards the realization of quantum networks based
on atom-like solid-state quantum emitters coupled to nanophotonic devices.
Specifically, we focus on experiments involving the negatively charged
silicon-vacancy color center in diamond. These emitters combine homogeneous,
coherent optical transitions and a long-lived electronic spin quantum memory.
We discuss optical and spin properties of this system at cryogenic temperatures
and describe experiments where silicon-vacancy centers are coupled to
nanophotonic devices. Finally, we discuss experiments demonstrating quantum
nonlinearities at the single-photon level and two-emitter entanglement in a
single nanophotonic device.
