Chapter 13 - Physical Implementations of Quantum Information Processing

Abstract

This chapter is devoted to several promising physical implementations of quantum information processing. The chapter starts with a description of physical implementation basics, di Vincenzo criteria, and an overview of physical implementation concepts (Section 13.1). The next section (Section 13.2) is related to nuclear magnetic resonance implementation, whose basic concepts are used in various implementations. In Section 13.3, the use of ion traps in quantum computing is described. Next, various photonic implementations (Section 13.4) are described, followed by quantum relay implementation (Section 13.5) and the implementation of quantum encoders and decoders (Section 13.6). Implementation based on optical cavity electrodynamics is further described in Section 13.7. Finally, the use of quantum dots in quantum computing is discussed in Section 13.8. After a short summary (Section 13.9), a set of problems (Section 13.10) is provided for self-study.
