    "abstract": "We review the use of quantum feedback for combatting the decoherence of\nSchroedinger-cat-like states in electromagnetic cavities, with special emphasys\non our recent proposal of an automatic mechanism based on the injection of\nappropriately prepared ``probe\u0027\u0027 and ``feedback\u0027\u0027 Rydberg atoms. In the latter\nscheme, the information transmission from the probe to the feedback atom is\ndirectly mediated by a second auxiliary cavity. The detection efficiency for\nthe probe atom is no longer a critical parameter, and the decoherence time of\nthe linear superposition state can be significantly increased using presently\navailable technology.",
