    "abstract": "We show how an initially prepared quantum state of a radiation mode in a\ncavity can be preserved for a long time using a feedback scheme based on the\ninjection of appropriately prepared atoms. We present a feedback scheme both\nfor optical cavities, which can be continuously monitored by a photodetector,\nand for microwave cavities, which can be monitored only indirectly via the\ndetection of atoms that have interacted with the cavity field. We also discuss\nthe possibility of applying these methods for decoherence control in quantum\ninformation processing.",
