    "abstract": "Based on a quantum analysis of two capacitively coupled current-biased\nJosephson junctions, we propose two fundamental two-qubit quantum logic gates.\nEach of these gates, when supplemented by single-qubit operations, is\nsufficient for universal quantum computation. Numerical solutions of the\ntime-dependent Schroedinger equation demonstrate that these operations can be\nperformed with good fidelity.",
