• Fundamental issues in quantum physics
Howard has been working in quantum measurement and control since his Honours project in 1991. In his PhD work he showed how quantum trajectory theory could be applied to the problem of quantum feedback, and this approach has become the accepted one. As a post-doc in Auckland he worked mainly on atom optics, in particular on atom lasers. Since 1996 he has held ARC research fellowships. The first at the University of Queensland was to work on adaptive measurements. The second at Griffith University is on the subject of non-Markovian quantum trajectories. This includes the so-called "realistic" quantum trajectories for non-ideal measurement devices which he introduced in 2002.
Since the establishment of the Centre of Excellence in 2003, Howard has been the program manager for the Griffith program. This has four aspects: i) modelling realistic measurements, ii) quantum feedback, iii) the quantum information-measurement interface, iv) the quantum computing-measurement interface.
