Information States in Control Theory: From Classical to Quantum
Matthew James
TL;DR
This paper explores the concept of information states in control theory, covering classical and quantum systems, and discusses their application in measurement feedback and quantum coherent feedback control.
Contribution
It provides a comprehensive overview of information states in both classical and quantum control, including recent generalizations to quantum coherent feedback.
Findings
Summarizes the use of information states in measurement feedback control.
Extends the concept to quantum coherent feedback control.
Highlights the theoretical framework connecting classical and quantum control theories.
Abstract
This paper is concerned with the concept of {\em information state} and its use in optimal feedback control of classical and quantum systems. The use of information states for measurement feedback problems is summarized. Generalization to fully quantum coherent feedback control problems is considered.
