Abstract

Abstract Spin‐entanglement of two electrons occupying two spatial regions – domains – is expressed in a compact form in terms of spin‐spin correlation functions. The power of the formalism is demonstrated on several examples ranging fromgeneration of entanglement by scattering of two electrons to the entanglement of a pair of qubits represented by a double quantum dot coupled to leads. In the latter case the collapse of entanglement due to the Kondo effect is analyzed (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
