Susanne Yelin, Atomic Cooperative Arrays: Bio‑Inspired Quantum Optics and Quantum Chemistry on Neutral‑Atom Array Quantum Computers

What is the potential of dense—cooperative—emitter arrays? These arrays, already known for their use in metrology and quantum information as efficient waveguides and mirrors, are now being studied in alternative geometries. Inspired by nature, we investigate chiral and helical structures, as well as ring‑shaped arrays.
In addition, we introduce a digital‑analog simulation framework for strongly correlated spin models using reconfigurable qubit arrays. Our toolbox—built on Floquet engineering and hardware‑optimized multi‑qubit gates—enables programmable real‑time Hamiltonian evolution, with an implementation proposal on Rydberg atom platforms. By combining snapshot measurements and single‑ancilla control, we extract excitation spectra and finite‑temperature susceptibilities from a single dataset. We illustrate this approach by computing key catalytic energy levels in a polynuclear transition‑metal complex and magnetic response in a two‑dimensional spin lattice.
