Robust entanglement with three-dimensional nonreciprocal photonic topological insulators
Robust entanglement with three-dimensional nonreciprocal photonic topological insulators
We investigate spontaneous and pumped entanglement of two level systems in the vicinity of a photonic topological insulator interface, which supports a nonreciprocal (unidirectional), scattering-immune and topologically-protected surface plasmon polariton in the bandgap of the bulk material. To this end, we derive a master equation for qubit interactions in a …
