Robust and optimal quantum control for some classes of linear quantum systems

As experimental quantum technology continues to
improve, the idea of manipulating microscale quantum
processes rather than just observing them is rapidly gaining
ground. In particular, the manipulation of quantum systems
using continuous measurement and feedback control has
generated increasing interest in the last few years due to its
potential applications in metrology, communications and other
quantum technologies. Also, the area of quantum control is of
theoretical interest, since it connects the well-developed field
of classical optimal control theory to fundamental questions
regarding the structure of information and disturbances
in quantum mechanics. Therefore, significant interest has
emerged in the area of quantum feedback control systems.
Extending classical control theory to the quantum domain;
i.e., to physical systems whose behaviour is not governed
by classical physics but dominated by quantum effects, has
become an important area of research. It is also an essential
prerequisite for the development of novel technologies such as
quantum information processing, as well as new applications in
quantum optics, quantum electronics and quantum chemistry.
The most effective strategies in classical control applications
involve feedback control. However, the implementation
of classical feedback control for quantum systems poses
severe challenges since quantum measurements tend to
destroy the state of the system (wave-packet reduction).
Nevertheless, the possibility of continuous monitoring and
manipulation on a natural time-scale has recently become
realistic for some quantum systems. This may be viewed
as a first step in the direction of closing the gap between
quantum feedback control and classical control theory.
