Description
We present progress on our experimental setup where we will use novel optical tweezers – derived from spatial light modulators – to manipulate the phonon spectrum of a two-dimensional ion crystal in a Paul trap [1]. This allows us to control the effective spin-spin interactions between the ions in order to realize and study various Hamiltonians of interest [2]. In particular, the pinning of a single ion can be used to create short-range spin-spin interactions. In 2D crystals, this can be used to quantum simulate spin Hamiltonians on a kagome lattice [2].
In one dimensional ion chains optical tweezers can be combined with oscillating electric fields in order to realize two-qubit geometrical phase gates [3]. This novel approach, combined with other well-established techniques, can be used to realize a novel architecture for quantum computing using trapped ions.
