| Abstract: |
Neutral atom-based qubits are highly scalable and controllable. With optical excitation of high-lying, strongly interacting Rydberg states, one can achieve on-demand, laser-controlled interactions for quantum logic operations. We present studies of entangling operations within a two-atom system employing individually-trapped ultra-cold cesium atoms that interact via direct laser coupling to a Rydberg level [1], where the Rydberg-dressed many-body Hamiltonian permits pairwise and beyond-pairwise interaction regimes. We also present a detailed study of a controlled-phase (CPHASE) gate that is insensitive to the detrimental effects of atomic motion and spurious light shifts, and that should enable high-quality entangling operation between atom pairs or within larger ensembles. Towards this end, we also present work towards using digital holography to generate reconfigurable trap arrays. [1] Y.-Y.
