In this paper we calculate the loss of fidelity due to quantum leakage for the Josephson charge qubit (JCQ) in virtue of the Mathieu functions. It is shown that for an present typical parameters of JCQ EJ/Ech ∼ 0.02, the loss of the fidelity per elementary operation is about 10 which satisfy the DiVincenzo’s low decoherence criterion. By appropriately improving the design of the Josephson junct...
