[<A HREF="http://www.slac.stanford.edu/spires/find/hep/www?key=8970998">SPIRES record</A>] <P> <B>Abstract</B>: Relying on a mathematical analogy of the pure states of the two-qubit system of quantum information theory with four-component spinors we introduce the concept of the intrinsic entanglement of spinors. To explore its physical sense we study the entanglement capabilities of the spin representation of (pseudo-) conformal transformation in (3+1)-dimensional Minkowski space-time. We find that only those tensor product structures can sensibly be introduced in spinor space for which a given spinor is not entangled. <P> <UL> <LI>Electronic copy of the preprint: <A HREF="http://arXiv.org/abs/1102.2544"> arXiv:1102.2544</A> <LI><A HREF="cite33.htm">Citations</A> <P> <LI>Misprints, errata, addenda: <UL> <LI> </UL> </UL> <HR> <A HREF="pub.htm">Up</A>, or back to: <A HREF="homepage.htm">home page of Klaus Scharnhorst</A> / <A HREF="http://www.nat.vu.nl/en/research/theoretical-physics/index.asp">Theoretical Physics</A> / <A HREF="http://www.nat.vu.nl/en/index.asp">Department of Physics and Astronomy</A> <HR> <ADDRESS> &#169; K.
