Dissipation-driven generation of two-qubit entanglement mediated by plasmonic waveguides

摘要: We study the generation of entanglement between two distant qubits mediated by surface plasmons a metallic waveguide. show that V-shaped channel milled in flat is much more efficient for this purpose than cylinder. The role misalignments dipole moments qubits, an aspect great importance experimental implementations, also studied. A careful analysis quantum dynamics system means master equation shows two-qubit essentially due to dissipative part effective qubit-qubit coupling provided plasmons. influence coherent external pumping, needed achieve steady-state entanglement, discussed. Finally, we pay attention question how get information experimentally on degree achieved system.
