The main area of my current research activity is to develop a theory of entanglement creation and entanglement transport in a noisy environment using the novel and realistic systems of trapped atoms. The innovation of this research is to consider creation and transfer of entanglement between excited multi-atom states and to consider realistic experimental situations of trapped atoms located at different positions, any geometrical configuration, any sample size including the dipole-dipole interaction and dissipation.
The specific aims of the research are:
1. Develop a technique to identify exact analytic expressions for the multi-quantum entangled states of a system of N atoms in different geometrical configurations including linear chain, two-dimensional and three-dimensional arrays, and closed-ring polymer chains.
2. Exploit the role of excited collective states for the controlled transfer and sharing of entanglement in multi-particle systems.
3. Identify coherent photon transfer processes between the collective entangled states with a particular emphasis on transfers between multi-photon entangled states without applying any dynamical control to the qubits.
4. Investigate practical implementations of the radiative properties of the multi-particle entangled systems in quantum information processing, quantum computing, and the reversible storage of photons.
5. Investigate entanglement creation in a noisy environment under realistic experimental situations of spatially extended systems of atoms in different geometrical configurations.
6. Identify coherent and incoherent photon transfer processes between the collective entangled states or internal atomic states, with a particular emphasis on transfers between multi-photon entangled states and to analyze conditions for decoherence-free storage of photons in collective multi-atom systems.
The above areas are of increasing scientific importance and have applications in quantum information, quantum computation, interferometry, laser cooling, laser technology and ultra-fast spectroscopy. My current research projects arise from the recent significant theoretical and experimental progress in trapping and cooling of isolated atoms and ions. Intensive theoretical work is underway to implement entanglement measures and information transfer processes in coupled atomic systems. I have a strong interest in working with experimental groups, and in developing theoretical ideas to the point where they can be tested with the present technology.
