The past decade has seen tremendous progress towards developing "quantum repeaters" – quantum memories that can store and retransmit photonic qubits for long-distance networking applications. Solid-state defects are particularly attractive memory candidates due to their long coherence times, bright optical transitions, and straightforward integration into nanophotonic structures. However, challenges in scalable fabrication have hampered the creation of large-qubit-number systems, and deployed demonstrations have remained elusive due to the lossy and noisy realities of telecommunications infrastructure. In this talk, I will present techniques developed to bring quantum repeaters based on solid-state defects out of the laboratory and into the field. I will first contextualize these challenges through on-going efforts toward memory-enhanced quantum networking over a 50 km deployed fiber testbed. I will then discuss pathways toward scalability through large-scale qubit characterization and novel architectures for both individual and multi-qubit systems. Together, these efforts represent a significant step in realizing scalable, memory-enabled quantum networks.
