Lower Order and Higher Order Entanglement in Four-Wave Mixing Process

Four-wave mixing of linear waves and solitons in fibers with higher-order dispersion.

We derive phase-matching conditions for four-wave mixing between solitons and linear waves in optical fibers with arbitrary dispersion and demonstrate resonant excitation of new spectral components via this process.

Four-wave mixing of linear waves ans solitons in fibers with higher-order dispersion

The use of any optical system, including fibers, for frequency conversion relies on the ability to satisfy so-called phase-matching conditions, which depend critically on the dispersive properties of the system, and on strong enough nonlinearity to allow a reduction in the threshold pump power. The recent surge of interest in theoretical and experimental studies of optical parametric processes ...

Reasoning about Entanglement and Separability in Quantum Higher-Order Functions

We present a logical approach to the separability analysis issue for a functional quantum computation language. This logic is inspired by previous works on logical analysis of aliasing for imperative functional programs. Both analyses share similarities notably because they are highly non-compositional. Nevertheless, the intrisic non determinism of quantum computation has a large impact on the ...

Generation of bright quadricolor continuous-variable entanglement by four-wave-mixing process

We propose an experimentally feasible scheme to produce bright quadricolor continuous-variable (CV) entanglement by a four-wave mixing process (FWM) with four-level atoms inside the optical ring cavities operating above threshold. The Stokes and anti-Stokes beams are generated via the pump beam (tuned close to one atomic transition) and the coupling beam (tuned to the resonance of another atomi...
