To achieve this, the resonant trap energies of the system are engineered in such a way that a single, well-defined eigenstate connects the initial and desired states and is isolated from the rest of the spectrum. We apply this procedure to the task of separating a small pre-defined number of particles (up to 10) from an initial cloud and show that it can be implemented in radio-frequency traps using experimentally realistic parameters.}, title = {Robust boson dispenser: Quantum state preparation in interacting many-particle systems}, volume = {96}, year = {2017} }
