Abstract |
|
|
| This study is oriented to discover new behaviour for quantum system under condition of three-qubit quantum entanglement
coupling with Kerr-like medium. Jaynes-Cummings model will be used to represent quantum entanglement coupling with Kerr-like
medium. In achieving these objectives, Jaynes-Cummings model will be modified to include three-qubit quantum system coupling with
Kerr-like medium for one-qubit transition. The three-qubit state will be interacting with Markovian and non-Markovian environment
which represented by Lorenztian spectral density. From the defined three-qubit Jaynes-Cummings model, lower bound concurrence
is used to measure quantum entanglement robustness. Based on the analysis quantum entanglement is more robust when Kerr-like
medium coupling strength increased for both Markovian environment and non-Markovian environment even though the influence of
quantum entanglement robustness is reduce when dipole-dipole interaction is getting stronger. |
