Linear Systems and Control Theory for Quantum Information

Hendra I. Nurdin, Naoki Yamamoto

Research output: Chapter in Book/Report/Conference proceedingChapter


This chapter illustrates several example applications of the theory of linear quantum systems to the analysis of problems of interest in quantum information processing and discusses two experimental demonstrations of real-time coherent feedback and measurement-based feedback control from the literature. The problems covered are dissipative generation of Gaussian states of single-mode oscillators, efficient enhancement of entanglement between traveling Gaussian fields, back-action evasion, perfect state transfer in a linear quantum network, and robust quantum amplification. The two experiments are demonstrations of enhancement of optical squeezing via static coherent feedback and generation of a spin-squeezed state in an atomic ensemble via measurement-based feedback control.
