    "abstract": "We solve exactly the non-Markovian dynamics of a cavity mode in the presence\nof a feedback loop based on homodyne measurements, in the case of a non-zero\nfeedback delay time. With an appropriate choice of the feedback parameters,\nthis scheme is able to significantly increase the decoherence time of the\ncavity mode, even for delay times not much smaller than the decoherence time\nitself.",
