    "abstract": "For a Bose condensate in a double-well potential or with two\nJosephson-coupled internal states, the condensate wavefunction is a\nsuperposition. Here we consider coupling two such Bose condensates, and suggest\nthe existence of a joint condensate wavefunction, which is in general a\nsuperposition of all products of the bases condensate wavefunctions of the two\ncondensates. The corresponding many-body state is a product of such superposed\nwavefunctions, with appropriate symmetrization. These states may be potentially\nuseful for quantum computation. There may be robustness and stability due to\nmacroscopic occupation of a same single particle state. The nonlinearity of the\ncondensate wavefunction due to particle-particle interaction may be utilized to\nrealize nonlinear quantum computation, which was suggested to be capable of\nsolving NP-complete problems.",
