Kerr-Nonlinearity-Induced Mode-Splitting in Optical Microresonators [PDF]

open access: yes, 2021
The Kerr effect in optical microresonators plays an important role for integrated photonic devices and enables third harmonic generation, four-wave mixing, and the generation of microresonator-based frequency combs.

Entanglement-Based Single-Photon Amplification With High Fidelity of Polarization Feature

open access: yesIEEE Photonics Journal, 2022
The amplification protocol of single-photon is an effective method to overcome the photon loss in the practical quantum communication. Here, we propose an entanglement-based single-photon amplification to nearly eliminate the vacuum state resulting from ...

Passive CPHASE Gate via Cross-Kerr Nonlinearities [PDF]

open access: yesPhysical Review Letters, 2016
A fundamental and open question is whether cross-Kerr nonlinearities can be used to construct a controlled-phase (CPHASE) gate. Here we propose a gate constructed from a discrete set of atom-mediated cross-Kerr interaction sites with counter-propagating photons. We show that the average gate fidelity $F$ between a CPHASE and our proposed gate increases

Amplification and cross-Kerr nonlinearity in waveguide quantum electrodynamics [PDF]

open access: yesPhysical Review A, 2020
We explore amplification and cross-Kerr nonlinearity by a three-level emitter (3LE) embedded in a waveguide and driven by two light beams. The coherent amplification and cross-Kerr nonlinearity were demonstrated in recent experiments, respectively, with a V and a ladder-type 3LE coupled to an open superconducting transmission line carrying two ...

Cross-Kerr nonlinearity in optomechanical systems [PDF]

open access: yesPhysical Review A, 2015
We consider the response of a nanomechanical resonator interacting with an electromagnetic cavity via a radiation pressure coupling and a cross-Kerr coupling. Using a mean field approach we solve the dynamics of the system, and show the different corrections coming from the radiation pressure and the cross-Kerr effect to the usually considered ...

Electromagnetically Induced Transparency in Media with Rydberg Excitons 2: Cross-Kerr Modulation

open access: yesEntropy, 2020
By mapping photons into the sample of cuprous oxide with Rydberg excitons, it is possible to obtain a significant optical phase shift due to third-order cross-Kerr nonlinearities realized under the conditions of electromagnetically induced transparency ...

Complete hyperentangled state analysis using weak cross-Kerr nonlinearity and auxiliary entanglement

open access: yesNew Journal of Physics, 2020
We present a new method for the complete analysis of hyperentangled Bell state and Greenberger–Horne–Zeilinger state in polarization and spatial-mode degrees of freedom, resorting to weak cross-Kerr nonlinearity and auxiliary frequency entanglement.

Kerr-Nonlinearity Assisted Exceptional Point Degeneracy in a Detuned PT-Symmetric System [PDF]

open access: yes, 2023
Systems operating at exceptional points (EPs) are highly responsive to small perturbations, making them suitable for sensing applications. Although this feature impedes the system working exactly at an EP due to imperfections arising during the ...
