    "abstract": "The two-qubit interaction Hamiltonian of a given physical implementation\ndetermines whether or not a two-qubit gate such as the CNOT gate can be\nrealized easily. It can be shown that, e.g., with the XY interaction more than\none two-qubit operation is required in order to realize CNOT. Here we propose a\ntwo-qubit gate for the XY interaction which combines CNOT with the SWAP\noperation. By using this gate quantum circuits can be implemented efficiently,\neven if only nearest-neighbor coupling between the qubits is available.",
