Quantifying and Tuning Entanglement for
Spin Systems

Nature Physics Oct. 2006 Cover

This project aims at advancing the research in the field of quantum information and quantum computations for better understanding of entanglement. The main thrust of this project is calculating entanglement for two-dimensional spin systems and relating it to decoherence time, which is a quantity measurable in experiments and of relevance in various proposals for traditional and quantum computer hardware. Of particular interest is to study one or more impurities embedded into such systems. The project carries a benchmark exact calculation in the field of entanglement in a 19-site two-dimensional spin system. The work will be collaboration with Prof. Sameh at Purdue.
