    "abstract": "We construct optimized implementations of the CNOT and other universal\ntwo-qubit gates that, unlike many of the previously proposed protocols, are\ncarried out in a single step. The new protocols require tunable inter-qubit\ncouplings but, in return, show a significant improvements in the quality of\ngate operations. Our optimization procedure can be further extended to the\ncombinations of elementary two-qubit as well as irreducible many-qubit gates.",
