Experiment Characterization,It is important to understand the behaviour and limitations of the apparatus. This chapter describes the characterisation of some of the more important aspects of the experimental apparatus.

Single-Qubit Gates,In this chapter we discuss the implementation and benchmarking of laser driven single-qubit gates. We discuss the sources of error, and determine what experimentally limits our gate fidelity.

Conclusion,In this thesis we have described work implementing high-fidelity laser-driven two-qubit and single-qubit gates in . hyperfine qubits. The best single-qubit and two-qubit gate errors we achieve are at least an order of magnitude below the fault-tolerant threshold for the best surface code error correction algorithms.

Introduction,t made many of the daunting theoretical and practical problems of such information processing tractable is this: the details of the physical device used for a computation do not matter – all ‘useful’ computers, no matter how they physically operate, are equivalent in terms of the classes of problems they can solve.

Trapped-Ion Qubits,d behaviour of a ‘crystal’ of trapped ions near their motional ground state. The shared motional degrees of freedom of such a crystal allow the implementation of quantum ‘logic gates’, i.e. multi-qubit entangling operations.
