中文摘要：

【正】 The Hamiltonian of a superconducting charge qubit with a configuration of dc SQUID contains an interac-tion between the LC oscillator part and charge qubit.This interaction may leads to quantum state collapse and revivalwhich degrades the charge qubits and leads to serious decoherence.An analysis shows that the existing charge qubitparameters do not lead to this phenomenon,which is very good for the superconducting charge qubit~
