An enhanced toolbox for larger and more versatile Rydberg atom arrays

Scalable and programmable Rydberg atom arrays are a promising platform for quantum simulation and quantum information processing. In this talk, we report on our work to scale up and enhance the programmability of Rydberg atom arrays. We first demonstrate the realization of defect-free arrays of up to 225 atoms using efficient atom-sorting algorithms based on multiple optical tweezers moving simultaneously. Next, we examine a building block of the platform comprising two atoms. By applying a Floquet drive to the atoms, we encounter several regimes of counterintuitive behavior unlike those usually accessed with a static Hamiltonian. For instance, we show that Rydberg blockade can be experienced by two atoms spaced farther than the static blockade radius. Further, the Floquet driving enables state-dependent population trapping and enhances the tunability between Rydberg blockade and anti-blockade. The presented techniques enrich the toolbox for controlling Rydberg atom arrays and open up possibilities for large-scale quantum simulations and new quantum information protocols.
