    "abstract": "We propose a scheme to reconstruct the state of a two-mode Bose-Einstein\ncondensate, with a given total number of atoms, using an atom interferometer\nthat requires beam splitter, phase shift and non-ideal atom counting\noperations. The density matrix in the number-state basis can be computed\ndirectly from the probabilities of different counts for various phase shifts\nbetween the original modes, unless the beamsplitter is exactly balanced.\nSimulated noisy data from a two-mode coherent state is produced and the state\nis reconstructed, for 49 atoms. The error can be estimated from the singular\nvalues of the transformation matrix between state and probability data.",
