    "abstract": "We consider how macroscopic quantum superpositions may be created from arrays\nof Bose-Einstein condensates. We study a system of three condensates in Fock\nstates, all with the same number of atoms and show that this has the form of a\nhighly entangled superposition of different quasi-momenta. We then show how, by\npartially releasing these condensates and detecting an interference pattern\nwhere they overlap, it is possible to create a macroscopic superposition of\ndifferent relative phases for the remaining portions of the condensates. We\ndiscuss methods for confirming these superpositions.",
