    "abstract": "The quantum dynamics of the Josephson junction system in the computational\nsubspace is investigated. A scheme for the controlled not operation is given\nfor two capasitively coupled SQUIDs. In this system, there is no systematic\nerror for the two qubit operation. For the inductively coupled SQUIDs, the\neffective Hamiltonian causes systematic errors in the computational subspace\nfor the two qubit operation. Using the purterbation theory, we construct a more\nprecise effective Hamiltonian. This new effective Hamiltonian reduces the\nsystematic error to the level much lower than the threshold of the fault\nresilent quantum computation.",
