Optical tweezers offer new opportunities to control and manipulate trapped ions with applications in quantum information processing. We consider the light potentials induced on trapped ions by an optical tweezer beyond the paraxial approximation. Longitudinal field components in the beam center cause spatially-dependent Rabi frequencies and AC Stark shifts, leading to unexpected qubit-motion...

Simulating non-adiabatic quantum dynamics, such as those governing photochemical processes in human vision or DNA resistance to UV, remains a major challenge [1]. Specifically, because these phenomena lie beyond the Born-Oppenheimer approximation, requiring both electrons and nuclei to be treated as an entangled quantum system, they are inherently hard to simulate classically. To describe...

Short Talk (15min)

In quantum computations and simulations, it is important to have methods for measuring properties of interest of the quantum system. For small systems containing only a few qubits, the gold standard is to reconstruct these properties via quantum state tomography (QST). However, the number of distinct measurement settings required to obtain a tomographically complete dataset scales...

Short Talk (15min)

We investigate quantum atom-ion scattering in the s-wave regime using a
hybrid apparatus comprising a single $^{138}$Ba$^{+}$ ion in a linear Paul trap and a $^{6}$Li Fermi gas. The atomic sample is prepared via sequential cooling in a magneto-optical trap (MOT) and a compressed MOT (cMOT) before confinement in a crossed optical dipole trap (xODT). Inelastic collision rates are manipulated...
