A local area quantum teleportation network based on an array of electrically activated graphene waveguides.

We present a scheme to generate a continuous variable (CV) multipartite entangled state using an array of plasmonic graphene waveguides that are activated by nonclassical driving microwave modes. Within this scheme, we can exploit the interaction of two light fields coupled to the same microwave mode in each waveguide to produce any type of multipartite Gaussian entangled state. A teleportation network is illustrated using the resultant CV multipartite entangled state.

High-fidelity quantum information transmission using a room-temperature nonrefrigerated lossy microwave waveguide.

Quantum microwave transmission is key to realizing modular superconducting quantum computers and distributed quantum networks. A large number of incoherent photons are thermally generated within the microwave frequency spectrum. The closeness of the transmitted quantum state to the source-generated quantum state at the input of the transmission link (measured by the transmission fidelity) degrades due to the presence of the incoherent photons.

Spatial solitons in an electrically driven graphene multilayer medium.

We investigate the evolution of coupled optical solitons in a multilayer graphene medium. The considered graphene medium is subjected to microwave voltage biasing. The coupled two optical solitons emerge through the electrical (i.

Non-local correlation dynamics in two-dimensional graphene.

We explore the non-local correlation dynamics in a Graphene sheet of disordered electrons in a two-dimensional honeycomb lattice, containing two sublattices, induced by the interaction range of impurity potentials of two Dirac points. The Bell function, uncertainty-induced non-locality, and concurrence are used to investigate the formation and robustness of the non-local correlation between the honeycomb lattice and the Dirac point. The generated lattice-point non-local correlations are explored when the lattice-point system is initially in the uncorrelated state.

Hybrid two-mode squeezing of microwave and optical fields using optically pumped graphene layers.

A measurable quadrature of a squeezed quantum state manifests a small uncertainty below the Heisenberg limit. This phenomenon has the potential to enable several extraordinary applications in quantum information, metrology and sensing, and other fields. Several techniques have been implemented to realize squeezed electromagnetic states, including microwave fields and optical fields.

Quantum microwave-to-optical conversion in electrically driven multilayer graphene.

In this paper, we propose a novel quantum approach for microwave-to-optical conversion in a multilayer graphene structure. The graphene layers are electrically connected and pumped by an optical field. The physical concept is based on using a driving microwave signal to modulate the optical input pump by controlling graphene conductivity.

Ultrashort pulse polarization control in silicon waveguides.

The nonlinear polarization dynamics of ultrashort optical pulses propagating in a low birefringent silicon waveguide is theocratically and numerically studied, with a static electric field applied across the waveguide. It is shown that the pulse shape and polarization evolution can be efficiently controlled by adjusting the magnitude of the applied dc field. It is also demonstrated that the polarization instability regime can be achieved in such waveguides - despite the presence of strong linear losses - by appropriately engineering the spatial distribution of the control field along the waveguide.

Electronic control of soliton power transfer in silicon nanocrystal waveguides.

We demonstrate numerically that the power transfer from one polarization component of a (1+ 1)D vector spatial soliton to the other in a birefringent nonlinear medium can be controlled via the electro-optic Kerr effect by varying the externally applied electric field. We show how several all-optical operations involving fundamental vector solitons can be electronically controlled. We also discover that the split-up of the higher-order vector solitons due to the two-photon absorption (TPA) can be suppressed by adjusting the external electric field.

Electrically and optically controlled cross-polarized wave conversion.

Light wave propagation in third-order nonlinear media with applied external electric field is investigated. Interplay between the nonlinear electro-optic and all-optical effects is examined theoretically. Energy exchange between the orthogonal light polarizations, the cross polarization conversion, results.
