Quantum correlations in fermionic and bosonic systems — •Kai Eckert¹, Maciej Lewenstein¹, and John Schliemann² — ¹Institut fuer Theoretische Physik, Universität Hannover, Appelstr. 2, D-30167 Hannover, Germany — ²Department of Physics, The University of Texas, Austin, TX 78712

The characterization of quantum correlations at distances where the indistinguishable character of the particles involved has to be taken into account is important for proposals of quantum information processing based on quantum dots technology.

Quantum correlations in two-fermion systems have recently been classified[1]. We generalize these results to special systems consisting of more than two fermions, especially analyzing criteria for possible slater decompositions. We also extend the results to bosonic systems.
