Atom chips provide a robust, compact, and scalable experimental setup that is ideal for the development, implementation, and testing of quantum-enhanced technologies such as quantum information processing, quantum simulation, and quantum metrology. On our atom chip, state-selective microwave near-field potentials allow for the coherent manipulation of both internal and motional states of ultracold atoms. Elastic collisional interactions are used to create multi-particle entanglement within a single Bose-Einstein condensate (BEC). Proposals to further use these microwave near-field potentials to realize a quantum phase gate with single atoms on an atom chip have been presented. We are currently investigating methods to experimentally entangle two small BECs. This will allow us to study quantum collisional phase shifts and investigate the possibility of using small BECs for quantum information processing.
