Title: State Preparation by Means of Optical Measurements

Speaker: Anne Nielsen

The ability to control and manipulate the state of quantum systems is
important in order to use such systems for technological purposes and
fundamental studies of quantum mechanics. Subjecting a system to
different Hamiltonians leads to different unitary time evolutions, but
the state collapse accompanying quantum mechanical measurements opens
several additional possibilities to change the state of a quantum
system in a desired way, and measurements thus constitute a powerful
state preparation tool. In the talk we investigate the influence of
measurements on the dynamics of quantum systems and provide examples
of various state preparation protocols that are based on optical
measurements.
