We are pleased to host a talk of former Kent student Philip Kitson, reporting on his PhD research:
Rydberg atom Networks for Quantum Technologies
In this talk, we present theoretical simulations of Rydberg excitations in engineered atomic arrays. Motivated by Atomtronics—a field of cold atom physics that aims to emulate electronic devices using matter waves as currents—we propose a novel paradigm in which current is carried by the controlled propagation of Rydberg excitations through circuits formed by atoms trapped in optical tweezers. We show how such Rydberg-based circuits can function as fundamental Atomtronic components, enabling the realisation of device-like behaviour at the excitation level rather than through particle transport. Building on this framework, we outline two key applications: the development of basic circuitry elements and the design of a quantum sensor for electric fields. This work lays the theoretical groundwork for a new class of Atomtronic devices based on Rydberg excitation transport.
