    "abstract": "This paper provides necessary and sufficient conditions for constructing a\nuniversal quantum computer over continuous variables. As an example, it is\nshown how a universal quantum computer for the amplitudes of the\nelectromagnetic field might be constructed using simple linear devices such as\nbeam-splitters and phase shifters, together with squeezers and nonlinear\ndevices such as Kerr-effect fibers and atoms in optical cavities. Such a device\ncould in principle perform `quantum floating point\u0027 computations. Problems of\nnoise, finite precision, and error correction are discussed.",
