COLLECTIVE BEHAVIOUR OF QUANTUM ASSEMBLIES
Quantum Wire and Quantum Dot Assemblies
theory of quantum information through models of quantum cellular automata and
artifical life and performing relevant computer simulations, using subdynamics,
functional analysis and C++, Java programming.
Studies to (a) understand steady state and dynamical behaviour of interacting
assemblies of quantum systems, and how
they may furnish the basis for future quantum information systems, (b) observe
interacting nanosystems in laser-cooled traps in order to understand the
behaviour of solid-state analogs.
