K. Scharnhorst: Entanglement capabilities of the spin representation of (3+1)D-conformal transformations. Quantum Information & Computation 13:11&12(2013)925-936 [arXiv:1102.2544]. [INSPIRE record]

Abstract: 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.
