Abstract: | We study the entanglement of thesuperconducting charge qubit with thequantized electromagnetic field in a microwave cavity. It can be controlleddynamically by a classical external field threading the SQUID within thecharge qubit. Utilizing the controllable quantum entanglement, we can demonstrate the dynamic process of the quantum storage of informationcarried by charge qubit. On the other hand, based on this engineered quantumentanglement, we can also demonstrate a progressive decoherence of chargequbit with quantum jump due to the coupling with the cavity field inquasi-classical state. |
