    "abstract": "Gaussian quantum channels have recently attracted a growing interest, since\nthey may lead to a tractable approach to the generally hard problem of\nevaluating quantum channel capacities. However, the analysis performed so far\nhas always been restricted to memoryless channels. Here, we consider the case\nof a bosonic Gaussian channel with memory, and show that the classical capacity\ncan be significantly enhanced by employing entangled input symbols instead of\nproduct symbols.",
