Quantum networks promise to enable provably secure communications, enhanced sensing, enhanced imaging, and distributed quantum information processing. However, networks implementations today are plagued by low generation rates and limited fidelity of distributed entanglement, which constrains near term applications. This talk explores the work I have pursued in exploring the tools we need to develop for near-term quantum networks. We will introduce quantum communications with some basic definitions, before proceeding to analyze quantum link architectures for entanglement generation for a diverse class of photonic encodings. I will explore quantum repeaters and quantum satellite networks briefly before discussing some applications.
