    "abstract": "We study how photon absorption losses degrade the bipartite entanglement of\nentangled states of light. We consider two questions: (i) what state contains\nthe smallest average number of photons given a fixed amount of entanglement?\nand (ii) what state is the most robust against photon absorption? We explain\nwhy the two-mode squeezed state is the answer to the first question but not\nquite to the second question.",
