    "abstract": "Quantum dissipation is studied within two model oscillators, the\nCaldirola-Kanai (CK) oscillator as an open system with one degree of freedom\nand the Bateman-Feshbach-Tikochinsky (BFT) oscillator as a closed system with\ntwo degrees of freedom. Though these oscillators describe the same classical\ndamped motion, the CK oscillator retains the quantum coherence, whereas the\ndamped subsystem of the BFT oscillator exhibits both quantum decoherence and\nclassical correlation. Furthermore the amplified subsystem of the BFT\noscillator shows the same degree of quantum decohernce and classical\ncorrelation.",
