Optical tweezers for trapped ion quantum simulation — •Rima X. Schüssler, Matteo Mazzanti, Clara Robalo Pereira, Nella Diepeveen, Louis Gallagher, Zeger Ackerman, Arghavan Safavi-Naini, and Rene Gerritsma — University of Amsterdam, Amsterdam, The Netherlands

Trapped ion crystals offer an advanced platform for quantum computation and simulation. However, limited control over the interactions between the ions constrains the range of accessible Hamiltonians.

In our experiment, we plan to combine trapped ions with microtraps in the form of optical tweezers. These additional potentials will allow us to manipulate the phonon mode spectrum and thereby control the spin-spin interactions of the ions in a Paul trap. We will use a high power 1030nm laser far detuned from any transition in Yb⁺. The tweezers will be produced by a spatial light modulator and focused on the ions to a waist of a few µm with a high NA objective. With the right tweezer pattern [1], we can then use the system to study various Hamiltonians of interest, for example, Hamiltonians on a kagome lattice in 2D ion crystals.
