Orbital and electronic entanglement in quantum teleportation schemes — •Anna Galler1,2 and Patrik Thunström3 — 1Graz University of Technology, 8010 Graz, Austria — 2Max Planck Institute for the Structure and Dynamics of Matter, 22761 Hamburg, Germany — 3Uppsala University, 75120 Uppsala, Sweden
With progress towards more compact quantum computing architectures, fundamental questions regarding the entanglement of indistinguishable particles need to be addressed. In a solid state device, this quest is naturally connected to the quantum correlations of electrons. In this talk, I analyse the formation of orbital (mode) and particle entanglement in strongly correlated materials due to the Coulomb interaction between the electrons. To study the role of the different forms of electronic entanglement, I propose and analyse three different electronic teleportation schemes: quantum teleportation within a molecule on graphene, a nitrogen-vacancy center, and a quantum dot array.
