 A modular neutral-atom architecture with a tweezer-cavity interface

Neutral atoms trapped in optical tweezers provide a versatile platform for quantum simulation, computation, and networking. Integrating these systems with optical cavities offers a promising route towards efficient atom-photon interfaces, enabling long-distance entanglement distribution and modular quantum architectures. Realizing such hybrid platforms, however, requires experimental systems that combine high repetition rates, continuous operation, and efficient quantum interconnects. In this talk, I will present the development of a new experimental platform based on individual ytterbium atoms trapped in optical tweezers and coupled to a high-finesse optical cavity that serves as a quantum interconnect. The system is designed for high-duty-cycle operation and uninterrupted operations through the use of a continuously replenished atom reservoir located in the science chamber. Future experiments will exploit the cavity-enhanced atom-photon interface to generate efficient single photons and atom-photon entanglement, while the programmable tweezer architecture enables scalable multi-qubit registers and modular quantum processors. Together, these capabilities establish a foundation towards modular quantum computing architectures in which optical cavities provide a native interface between local neutral-atom registers and remote quantum nodes.
