RESEARCH
Progress
in science often comes from combining different ideas and approaches in
seemingly unrelated fields. One of the most successful examples of this
is quantum information sciences,
where the combination of information theory and quantum mechanics has
lead to new and deep fundamental insights as well as to ideas for
radically new applications in computing and communication technologies.
In addition, its role for better understudying of physical
processes in biological systems, likewise in black hole is heading in a
promising direction. Our current research interests are mainly in using
quantum information approach to understand and simulate dynamics in
various physical systems, ranging from condensed matter systems and
effects in high energy systems. Below is a brief outline of
topics we are interested in.
Research
Interests
- Quantum
Information Theory : Quantum algorithms – quantum walks, entanglement
in quantum many body systems, quantum percolation in complex networks
and information flow, channel capacity, quantum state transfer,
quantum memories, adiabatic quantum computing (stimulated annealing of
quantum system), and quantum open systems.
