Abstract: Programmable arrays of ultracold Rydberg atoms offer an intriguing platform for quantum information processing. In this talk, I will introduce two novel architectures designed to address scalability challenges for neutral atoms trapped in optical tweezers.
The first architecture is a low-vibration, high-optical-access cryogenic platform, developed during my time at JILA, which significantly enhances the atom vacuum lifetime. In this system, we demonstrate a 3000-second atom trap lifetime, enabling the creation of defect-free atom arrays with thousands of qubits. Additionally, we achieve ground-state qubit manipulation using an integrated microwave antenna and demonstrate two-photon coherent control of Rydberg states.
The second architecture is currently under construction at the University of Trieste. This system integrates three key components: a quantum computing unit for executing arbitrary operations, a tweezer-cavity interface for cavity quantum electrodynamics (cQED) and quantum networking experiments, and an atom reservoir to enable fast experimental cycle times and uninterrupted operations.
