abstract = {We consider how the Hamiltonian Quantum Computing scheme
introduced in (2016 New J. Phys. 18 023042) can be
implemented using a 2D array of superconducting transmon
qubits. We show how the scheme requires the engineering of
strong attractive cross-Kerr and weak flip-flop or hopping
interactions and we detail how this can be achieved. Our
proposal uses a new electric circuit for obtaining the
attractive cross-Kerr coupling between transmons via a
dipole-like element. We discuss and numerically analyze the
forward motion and execution of the computation and its
dependence on coupling strengths and their variability. We
extend (2016 New J. Phys. 18 023042) by explicitly showing
how to construct a direct Toffoli gate, thus establishing
computational universality via the Hadamard and Toffoli gate
or via controlled-Hadamard, Hadamard and CNOT.},
