Robust and optimal quantum control for some classes of linear quantum systems
Aline I Maalouf

A
s 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
continuousmonitoringandmanipulationonanatural 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
betweenquantumfeedback control and classical control theory.
In this talk, I will define robust and optimal quantum control
