%0 Journal Article %T Universality of single quantum gates %A Bela Bauer %A Claire Levaillant %A Michael Freedman %J Mathematics %D 2014 %I arXiv %X We supply a rigorous proof that an open dense set of all possible 2-qubit gates G has the property that if the quantum circuit model is restricted to only permit swap of qubits lines and the application of G to pairs of lines, then the model is still computationally universal. %U http://arxiv.org/abs/1404.7822v3
