"Trapping and manipulating cold Rydberg atoms – from quantum information to antimatter physics"
Professor Stephen Hogan
Department of Physics and Astronomy
University College London

---

The development of experimental methods to control the motion of, and trap, atoms and molecules in highly-excited Rydberg states using inhomogeneous electric fields [1] has opened new opportunities in a range of research areas, from quantum information processing [2,3] to antimatter physics [4].
In this talk I will describe these experimental methods with the example of a chip-based trap architecture that we have recently developed. I will then present the results of experiments in the areas of (i) hybrid quantum information processing, (ii) low-energy atom-molecule scattering [5], and (iii) positronium physics in which we exploit these techniques.
