Figure 1

(a) Illustration of the optical system used for creating the traps. Collimated laser light is reflected from the SLM through a Fourier 2f arrangement to form the intensity pattern in the trapping plane. f denotes the lens' focal length, see the Methods section for definition of the remaining symbols. The pattern shown in the trapping plane is the atomtronic OR-gate, which we use to test our method. (b) A cartoon of the constraints and the variables to be solved for. The modulus of the light field is fixed in the SLM plane and we wish to solve for the kinoform to produce the correct modulus with no constraints on the phase in the trapping plane.
