    "abstract": "To implement quantum information processing, microwave fields are often used\nto manipulate superconuducting qubits. We study how the coupling between\nsuperconducting charge qubits can be controlled by variable-frequency magnetic\nfields. We also study the effects of the microwave fields on the readout of the\ncharge-qubit states. The measurement of the charge-qubit states can be used to\ndemonstrate the statistical properties of photons.",
