TL;DR: It is shown that large values for the concurrence are attainable for qubit-qubit distances larger than the operating wavelength by using plasmonic waveguides that are currently available.

TL;DR: It is shown that a single rectangular hole in a metallic film exhibits transmission resonances that appear near the cutoff wavelength of the hole waveguide, and this resonant transmission process is accompanied by a huge enhancement of the electric field at both entrance and exit interfaces of thehole.

TL;DR: These modes are found to exhibit superior confinement while showing similar propagation loss as compared to other subwavelength guiding configurations, and it is shown that mode focusing can be realized by gradual modification of the wedge geometry along the mode propagation direction.

TL;DR: It is demonstrated that textured closed surfaces, i.e., particles made of perfect electric conductors (PECs), are able to support localized electromagnetic resonances with properties resembling those of localized surface plasmons (LSPs) in the optical regime and a metamaterial approach is presented that captures the basic ingredients of their electromagnetic response.

TL;DR: In this article, the waveguid-ing elements are based on plasmonic and metamaterial notions and consist of an easy-to-manufacture periodic chain of metallic box-shaped elements protruding out of a metallic surface.
