    "abstract": "We present solutions of the time dependent Schrodinger equation for a SQUID\nring coupled to an electromagnetic field, both treated quantum mechanically. We\nthat show the SQUID ring can be used to create a maximally entangled state with\nthe em field that without dissipation remains constant in time. Using methods\nfamiliar in quantum optics, we extend the model to include the effects of\ncoupling this system to a dissipative environment. With this model we show that\nalthough such an environment makes a noticeable difference to the time\nevolution of the system, it need not destroy the the entanglement of this\ncoupled system over time scales required for quantum technologies.",
