Abstract
The SQUID qubits in a microwave cavity were investegated with the realization of quantum information transfer (QIT). With a high fidelity the QIT and entanglement with two-SQUID qubits were achieved. The SQUIDs used in the experiment were consisting a josephson tunnel junction in superconducting loop. It was found that SQUID qubits in a microwave cavity can be achieved using strong coupling limit. A path for production of nonclassical microwave source and quantum communication was provided by the SQUID systems.
