Orbital and electronic entanglement in quantum teleportation schemes

Blog Article

With progress toward 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.Here, we analyze the formation of orbital (mode) and particle welding sweater entanglement in strongly correlated materials due to the Coulomb interaction between the electrons.

We extend the analysis to include spectroscopic measurements of the electronic structure, with here a particular focus on the photoemission process.To study the role of the different forms of electronic entanglement, including the effect of particle-number superselection rules, we propose and analyze three different electronic teleportation schemes: quantum teleportation within (i) a molecule on graphene, (ii) a nitrogen-vacancy center, and (iii) a quantum dot array.
