Scalable and programmable neutral atom arrays are a promising platform for quantum simulation and quantum information processing. In this talk, we report on recent work to advance neutral atom arrays on two fronts: scaling up the array size and programming Floquet-tailored Rydberg interactions. First, we demonstrate the realization of large defect-free arrays containing more than two hundred singly-trapped atoms using efficient atom-sorting algorithms. Second, we use Floquet frequency modulation to achieve Rydberg-blockade entanglement beyond the blockade radius, thereby increasing the entanglement range in neutral atom quantum processors. Further, we find that the Floquet frequency modulation protects the entangled state coherence and enables new pathways to realizing strongly-interacting states. Our Floquet work redefines the ability to access the paradigmatic regimes of Rydberg blockade versus anti-blockade and opens the door to realizing more connected, coherent, and versatile neutral atom processors with a single approach.

About Australia - New Zealand Cold Atom Seminars

This new initiative hosts a seminar once a month for the Australia – New Zealand cold atom research community.  The purpose is to encourage and facilitate ongoing discussions and collaboration in the local community.  Talks should be less than 40 minutes in length to allow ample time for questions and discussion.

Seminars will be held on the last Friday of the month (except for December) at 1pm Melbourne time (which is normally 3pm New Zealand time).  While the primary format is online via Zoom, various institutions will host the seminar in local seminar rooms.  The Zoom link is https://uqz.zoom.us/j/88604569495

You can sign up for announcements for the seminars at this webpage:

Seminars are recorded, and past seminars can be accessed from this web page.
