Expanded quantum science applications for single atoms in silicon

Abstract

The control and measurement of the quantum state of single phosphorus atoms in silicon has opened up vast new avenues for exploration of quantum effects. The work outlined in this thesis describes the development of several of these avenues, extending the applications of the system for quantum science. The electron and nuclear states of the phosphorus donor have been utilised as a quantum memory, experimental means have been developed to optically address these quantum states, and experiments were developed to probe the nature of causality and time-symmetry in quantum systems.
