"scalable programmable bosonic network... set of bosonic modes connected to each other via controllable beam splitters... program phase and ratio of each beam splitter by controlling phase and duration of individually addressed laser beams... input and output of phonons in processor deterministically prepared and detected... minimal loss of phonons... phonons of the ions in a harmonic potential instead of photons enabling generation of quantum states of phonons deterministically without losing phonons"
