Thesis

Novel optical and microwave systems for use in precision measurement, quantum memory and quantum computation

Summary

This project covers two closely aligned areas of research of precision and quantum measurement:

(1) Laser cooling and trapping of Yb with the aim of producing a state-of-the-art optical atomic clock, the first cold-atom clock in Australia. The Yb atoms, in the UWA experiment, will be constrained by a light field producing a periodic array of atoms (optical lattices).

(2) Measurement and control of the interaction of microwave and optical transitions in paramagnetic impurity ions in a crystal lattice. The systems under study will include rare-earth-doped YSO and YAG crystals, NV-centers in diamond, organic molecules, chromium ions in ruby, fullerene cages and P-donors in silicon.

Why my research is important

The Yb optical clock will form part of the UWA ground station for the Atomic Clock Ensemble in Space (ACES) mission, set to be launched in 2016 (which is a high priority mission set for the International Space Station). The system will be used for a variety of tasks, such as timekeeping, GPS and testing for changes in fundamental constants. Effect of quantum tunnelling will also be studied - an aspect that has not been explored in depth in atomic clocks.

The knowledge obtained by studying interactions of paramagnetic impurity ions in crystals will be used to transfer quantum information between the GHz frequency range, with optical quantum networks and atomic qubits for the implementation of the distributed quantum information processing as well as for the quantum communication.
