Entanglement transfer via cross-Kerr nonlinearity

Acta Physica Sinica, 2008
We propose a scheme for realizing entanglement transfer based on the cross-Kerr nonlinear interaction between field-modes. By using this scheme the entanglement can be transferred from the field-states with discrete variables to the field-states with continuous variables.

Entanglement concentration for arbitrary four-particle linear cluster states

Scientific Reports, 2017
Cluster states, whose model are a remarkably rich structure in measurement-based quantum computation, hold high degree of entanglement, while entanglement is very fragile during the process of transmission because of the inevitable interaction with the ...

Optical solitons and stability analysis with coupled nonlinear schrodinger’s equations having double external potentials

Results in Physics, 2019
We consider coupled nonlinear Schrodinger equation (CNLSE) of the Gross-Pitaevskii-type, with linear mixing and nonlinear cross-phase modulation. Motivated by the study of matter waves in Bose-Einstein condensates and multicomponent (vectorial) nonlinear

Photonic two-qubit parity gate with tiny cross–Kerr nonlinearity [PDF]

Physical Review A, 2012
The cross-Kerr nonlinearity (XKNL) effect can induce efficient photon interactions in principle with which photonic multiqubit gates can be performed using far fewer physical resources than linear optical schemes. Unfortunately, it is extremely challenging to generate giant cross-Kerr nonlinearities.

Filtration mapping as complete Bell state analyzer for bosonic particles

Scientific Reports, 2021
In this paper, we present the approach to complete Bell state analysis based on filtering mapping. The key distinctive feature of this appoach is that it avoids complications related to using either hyperentanglement or representation of the Bell states ...

Polarization Rotation in Silicon Waveguides: Analytical Modeling and Applications

IEEE Photonics Journal, 2010
The efficient use of optical nonlinearities in silicon is crucial for the implementation of silicon-based photonic devises. In this paper, we present an approximate analytical study of nonlinear polarization rotation in silicon-on-insulator (SOI ...

Spatially structured multi-wave-mixing induced nonlinear absorption and gain in a semiconductor quantum well

Scientific Reports, 2022
We have studied two-dimensional absorption and gain spectrum in an asymmetric semiconductor triple-coupled-quantum-well (TCQW) nanostructure. Four subband transitions are coupled by using four coherent fields in a close-loop configuration to introduce ...

The phase of darkness – measuring the phase of a dark pulse [PDF]

EPJ Web of Conferences
Dark optical solitons are solutions to the nonlinear Schrödinger equation in normal dispersion media with positive Kerr nonlinearity, exhibiting a discrete π phase jump. These solitons are valuable to applications within telecommunication.

Noise-resistant optomechanical entanglement via cross-Kerr effect

Fundamental Research
We propose a scheme to achieve entanglement between cavity mode and mechanical mode by breaking dark mode (DM) effect via cross-Kerr effect. This DM induced by the coupling of multiple degenerate mechanical modes to a common cavity mode, is decoupled ...
