    "abstract": "We study the entanglement of the superconducting charge qubit with the\nquantized electromagnetic field in a microwave cavity. It can be controlled\ndynamically by a classical external field threading the SQUID within the charge\nqubit. Utilizing the controllable quantum entanglement, we can demonstrate the\ndynamic process of the quantum storage of information carried by charge qubit.\nOn the other hand, based on this engineered quantum entanglement, we can also\ndemonstrate a progressive decoherence of charge qubit with quantum jump due to\nthe coupling with the cavity field in quasi-classical state.",
