    "abstract": "We show, within the circuit model, how any quantum computation can be\nefficiently performed using states with only real amplitudes (a result known\nwithin the Quantum Turing Machine model). This allows us to identify a 2-qubit\n(in fact 2-rebit) gate which is universal for quantum computing, although it\ncannot be used to perform arbitrary unitary transformations.",
