Quantum networks promise to enable provably secure communications, enhanced sensing, enhanced imaging and distributed quantum information processing. However, low generation rates and the quality of distributed entanglement will constrain near-term quantum networks. This dissertation explores near-term quantum networks for shared entanglement generation. We begin by reviewing the theoretical limits of quantum communications and the principles underlying quantum links and repeaters, including various photon-based and memory qubit encodings. We then analyze quantum link architectures for entanglement generation for a diverse class of photonic encodings. We subsequently analyze linear-chain quantum repeater networks; we discuss improvements to the rate-vs.-loss scaling with time-multiplexed entanglement swaps and the practical limitations associated with finite memory coherence times and buffer capacities. We propose satellite-assisted quantum links as an alternative to quantum repeaters, presenting and analyzing several candidate link architectures.
