| Outline of Final Research Achievements |
The research has shown it is possible to create Rydberg atoms next to an optical nanofibre. We have achieved excitation as high as n=68 for D states. We can extend this to higher states by controlling the position of the ground state atoms prior to the excitation pulse to the Rydberg state. This opens up many new avenues of research, particularly in the area of waveguide quantum electrodynamics, contributing to advances in quantum optics and possibly the development of Rydberg atom-waveguide quantum networks. Our work has successfully been recognized by the international community and has led several other laboratories worldwide to commence experimental endeavors on Rydberg atoms and optical nanofibres. We have published several peer-reviewed articles related to the experimental and theoretical outcomes and have given a number of invited talks at conferences in many countries including the USA, Spain, Germany, United Kingdom, and Japan on the outcomes.

| Academic Significance and Societal Importance of the Research Achievements |
In quantum technologies, atoms are ideal for storing quantum informatio, acting as quantum nodes and photons transfer this information, creating a quantum “bus” for data. A loss of photons can occur during the transfer. This can be surmounted by using optical nanofibres in the atom system.
