Tight-binding lattice models allow the creation of bound composite objectswhich, in the strong-interacting regime, are protected against dissociation. Weshow that a local impurity in the lattice potential can generate a coherentsplit of an incoming bound particle wave-packet which consequently produces aNOON state between the endpoints. This is non trivial because when finitelattices are involved, edge-localisation effects make their use fornon-classical state generation and information transfer challenging. We derivean effective model to describe the propagation of bound particles in aBose-Hubbard chain. We introduce local impurities in the lattice potential toinhibit localisation effects and to split the propagating bound particle, thusenabling the generation of distant NOON states. We analyse how minimalengineering transfer schemes improve the transfer fidelity and we quantify therobustness to typical decoherence effects in optical lattice implementations.Our scheme potentially have an impact on quantum-enhanced atomic interferometryin a lattice.
