    "abstract": "Entanglement distribution between trapped-atom quantum memories, viz. single\natoms in optical cavities, is addressed. In most scenarios, the rate of\nentanglement distribution depends on the efficiency with which the state of\ntraveling single photons can be transferred to trapped atoms. This loading\nefficiency is analytically studied for two-level, $V$-level, $\\Lambda$-level,\nand double-$\\Lambda$-level atomic configurations by means of a system-reservoir\napproach. An off-resonant non-adiabatic approach to loading $\\Lambda$-level\ntrapped-atom memories is proposed, and the ensuing trade-offs between the\natom-light coupling rate and input photon bandwidth for achieving a high\nloading probability are identified. The non-adiabatic approach allows a broad\nclass of optical sources to be used, and in some cases it provides a higher\nsystem throughput than what can be achieved by adiabatic loading mechanisms.\nThe analysis is extended to the case of two double-$\\Lambda$ trapped-atom\nmemories illuminated by a polarization-entangled biphoton.",
