Linking remote quantum systems promises a host of new applications, ranging from distributed quantum computing to entanglement enhanced telescopes. Long distance quantum networks will require many nodes consisting of interfaces between local quantum memories and optical photons. While there are many contenders for these quantum nodes, nanophotonic implementations are particularly attractive: Once a single system works, it can be reproduced many times at minimal marginal costs.

Here I will report on recent experiments with nanophotonic memories, including the entanglement of two mechanical memories in a silicon photonics platform and a nanophotonic quantum register in diamond. Finally, I will discuss the prospects of these nanophotonic devices for deployment in near-term multi-node quantum networks.
