    "abstract": "We investigate the synthesis of continuous-variable two-mode unitary gates in\nthe setting where two modes A and B are coupled by a fixed quadratic\nHamiltonian H. The gate synthesis consists of a sequence of evolutions governed\nby Hamiltonian H interspaced by local phase shifts applied to A and B. We\nconcentrate on protocols that require the minimum necessary number of steps and\nwe show how to implement the beam splitter and the two-mode squeezer in just\nthree steps. Particular attention is paid to the Hamiltonian x_A p_B that\ndescribes the effective off-resonant interaction of light with the collective\natomic spin.",
