    "abstract": "Linear superpositions of macroscopically distinct quantum states (sometimes\nalso called Schr\\\"odinger cat states) are usually almost immediately reduced to\na statistical mixture if exposed to the dephasing influence of a dissipative\nenvironment. Couplings to the environment with a certain symmetry can lead to\nslow decoherence, however. We give specific examples of slowly decohering\nSchr\\\"odinger cat states in a realistic quantum optical system and discuss how\nthey might be constructed experimentally.",
