Scheme for generation of three-photon entangled W state assisted by cross-Kerr nonlinearity and quantum dot [PDF]
Scientific Reports, 2019 We represent an optical scheme using cross-Kerr nonlinearities (XKNLs) and quantum dot (QD) within a single-sided optical cavity (QD-cavity system) to generate three-photon entangled W state containing entanglement against loss of one photon of them.

Optical scheme for generating hyperentanglement having photonic qubit and time-bin via quantum dot and cross-Kerr nonlinearity [PDF]
Scientific Reports, 2018 We design an optical scheme to generate hyperentanglement correlated with degrees of freedom (DOFs) via quantum dots (QDs), weak cross-Kerr nonlinearities (XKNLs), and linearly optical apparatuses (including time-bin encoders).

Hyper-parallel nonlocal CNOT operation with hyperentanglement assisted by cross-Kerr nonlinearity. [PDF]
Sci Rep, 2019 AbstractImplementing CNOT operation nonlocally is one of central tasks in distributed quantum computation. Most of previously protocols for implementation quantum CNOT operation only consider implement CNOT operation in one degree of freedom(DOF).

Quantum Behavior of a PT -Symmetric Two-Mode System with Cross-Kerr Nonlinearity [PDF]
Symmetry, 2019 Quantum behavior of two oscillator modes, with mutually balanced gain and loss and coupled via linear coupling (including energy conserving as well as energy non-conserving terms) and nonlinear cross-Kerr effect, is investigated. Stationary states are found and their stability analysis is given.

Cavity-Free Optical Isolators and Circulators Using a Chiral Cross-Kerr Nonlinearity
Physical Review Letters, 2018 Optical nonlinearity has been widely used to try to produce optical isolators. However, this is very difficult to achieve due to dynamical reciprocity. Here, we show the use of the chiral cross-Kerr nonlinearity of atoms at room temperature to realize optical isolation, circumventing dynamical reciprocity.

Cross-Kerr nonlinearity: a stability analysis [PDF]
Mathematics of Quantum Technologies, 2015 AbstractWe analyse the combined effect of the radiation-pressure and cross-Kerr nonlinearity on the stationary solution of the dynamics of a nanomechanical resonator interacting with an electromagnetic cavity. Within this setup,we show how the optical bistability picture induced by the radiation-pressure force is modi fied by the presence of the cross ...

Polychromatic Kerr nonlinearity within electromagnetically induced transparency window
Results in Physics, 2021 We study the nonlinear effect in a three-level atomic system in Λ configuration. As two or more fields are confined within the common electromagnetically induced transparency (EIT) window, they directly disturb EIT dark state at the same time, which ...
