Quantum computation with trapped ions and atoms
Felix Rohde, Jürgen Eschner · Oxford University Press eBooks · 2011
This chapter reviews the basic experimental techniques which enable quantum information processing (QIP) with trapped ions and, more briefly, with trapped atoms. In particular, it is explained how the fundamental concepts of quantum computing, such as quantum bits (qubits), qubit rotations, and quantum gates, translate into experimental procedures in a quantum optics laboratory. Furthermore, the recent progress of quantum computing with ions and atoms is summarised, and new approaches to meet the future challenges of scaling up QIP and of atom-photon qubit interfacing are discussed. The chapter is intended to provide an intuitive understanding of the subject and enable the non-specialist student to appreciate the paradigmatic role and the potential of trapped single ions and atoms in the field of quantum computation or, more generally, of quantum optical information technology.
