Abstract: We provide a scheme for the generation of entangled number states ofBose-Einstein condensates in multiple wells with cyclic pairwise connectivity.The condensate ground state in a multiple well trap can self-evolve, when phaseengineered with specific initial phase differences between the neighboringwells, to a macroscopic superposition state with controllable entanglement -to multiple well generalization of double well NOON states. We demonstratethrough numerical simulations the creation of entangled states in three andfour wells and then explore the creation of -larger- entangled states wherethere are either a larger number of particles in each well or a larger numberof wells. The type of entanglement produced as the particle numbers, orinteraction strength, increases changes in a novel and initially unexpectedmanner.
